    The duplicate variable problem is a known issue with a complex fix. Noone has gotten to fixing it yet...

    I had the source code unchanged. The text file sample.txt in the sudirs differ a lot. The only difference, I see, is that I put the object files not in the two subdirs, but I generated Product10.wixobj anbd Product11.wixobj. I worked with Wix V3 3.0.3120.0. Is "torch -p ..." a must?  I thought -xi automatically includes -xo and -o.

    "Your WiX toolset version should be at least 3.0.3001.0" Where can I find the 3.0.3001.0 binaries?  Do have to build WiX myself?  The latest version I see on sourceforge is  3.0.2925.0.

    Think of references inside a <PatchFamily> as a way of selecting exactly what you want in your patch. You have 2 options: 1: No <PatchFamilies> with references inside them will result in all the differences between your target and upgrade being included. 2: Including <PatchFamilies> with references inside them will result in only those things that are referenced being included in the patch. Does that answer your question?

    I have a problem for creating patch file : warning PYRO1079 : The cabinet 'RTM.cab' does not contain any files.  If this installation contains no files, this warning can likely be safely ignored.Otherwise, please add files to the cabinet or remove it. error PYRO0227 : The transform being built did not contain any differences so it could not be created. I certainly two files *.wixout are different.

    Please log a bug with full details on SourceForge so we can take a look at this and hopefully get it fixed. The more information you can provide to help us reproduce this, the better. If you dont want to share your source with the world but are willing to provide it just to me, let me know.

    The servicing story for the Wix3 msi is major upgrade and not patch. They are not designed to be patched. The product code changes build to build. This does not mean it couldnt be patched but probably shouldnt be. The other problem you are hitting is probably because the patching tools work for two msi's built with the same version of WiX. There are often changes between wix builds that make patching not possible. This is probably the reason you are seeing the exceptions while patching. Can you file a bug on Sourceforge with more details of the exception so we can try to figure out how to provide a better error message? Thanks!

    Hi all, my problem is that I have a few custom actions in my base installer(rtm) and have the same ones in my latest one,  the differences are just base in the files contain within it(add, erased or update) but I keep having thir error: torch.exe : error TRCH0001: Item has already been added. Key in dictionary: 'InstallExecuteSequence/ConfigureIIs'  Key being added: 'InstallExecuteSequence/ConfigureIIs' I thought that if the custom action is present in both installer it's shouldn't  be taken as a difference by torch... am I right? I would really appreciate the help

    I am considering switching to a new patching system and I wonder how does it deal with, in my case, troublesome file sequence numbers? Namely, I have so many files changing between the versions (but changes themeselves are typically very small) that I am afraid I will hit a 16-bit integer limit on file index. There is a way to upgrade this field to 32 bit integer but I have no idea how to accomplish that in WiX? Wishful thinking: could it be that we are automagically spared from having to think about the file sequence numbers with this new system? Just use it and everything will be just fine ... dreaming ...

    Sequences in your upgrade are ignored and any files with differences are put in the media entry you authored in your patch. This media entry should be higher than your last sequence. Wix v3 automatically sets the column type of the sequence to i4 so you shouldnt have any problems with a large number of files.

  • Anonymous
    July 29, 2008
    Could you, please, elaborate a bit more on 'this media entry should be higher than your last sequence' ? If I start with media at 5000 and patch 10 files my next entry should be 5010? Then, the next patch, if there are 15 files to be patched, would push this number to 5025?

  • Anonymous
    August 16, 2008
    It needs to be higher than the last sequence in the baseline you are targeting. So if the last sequence in your original product is 5000 then you need to make the media at least 5001 for all patches that apply to the original product. The more I think about this the more I think that we can do the right thing for you in the tools but right now, this is something you have to handle.

    Yes, that helps, thanks! However, I didn't explain why did I stick to using -xo option. It is because I wanted wixpdb that includes binaries, as I can't exactly reproduce original MSI build environment paths when patching. However light help says:  -bf        bind files into a wixout (only valid with -xo option) So I guess I would have to start working with administrative image and -ax option to torch.

  • Anonymous

    Yes, if you didn't keep your original build around then you are likely going to find admin image patching to be more friendly to you. Also, if you build a product that you would like to create patches for, you should not update to a newer version of WiX when you build the upgrades or patches. Stick to exactly the same toolset or you are likely to hit problems.

    Peter - I have a question about the source attribute: Source=".$(var.Version)Sample.txt" If your going from v1.0 to v1.1, and the file is new to v1.1, how do you keep a build of v1.0 from aborting?  I am having a hard time figuring out how to structure my versioning folders, where files are introduced in subsequent minor versions, while keeping a common set of wxs files.  Using $(var.Version) seems to be part of the answer... Thanks,

    Hi Troy, One option would be to use the preprocessor to only include the new content in the higher version. Not sure if this xml sample is going to come through. <?if $(var.Version) > 1.0 ?> Put your added content here. <?endif ?> If that doesn't make things easier for you, I can try to think of other ways.

    Hi Peter - This worked!  Thanks.  However I ran into another small issue.  It seems like the patch process will only work for new or existing files .. meaning we are pushing the entire file.  It appears my ComponentRefs, which reference util:XmlConfig patches, are not being applied when I pass in the msp.  Is there some trick to getting these applied?  I am wondering if the "diff" process, using torch, somehow skips these? Thanks.

    I have a multi-language installer and want to make a corresponding multi-language patch. I went through your posts about patching with WiX v3. I'm wondering if the patching system in WiX v3 is able to produce a multi-language patch. If so, could you list the step-by-step instructions based on the example in this blog entry? Thank you.

  • Anonymous
    May 25, 2009
    What method are you using to create your multi-language installer? Are you using language transforms applied to the database at runtime? If so, are you using a bootstrapper to apply the right transform? Unfortunately, I haven't seen a good answer to shipping multi-language patches that doesn't involve writing a bunch of customactions to apply localized data to the patch at runtime depending on the current locale.

    Hi Peter, Thank you for the quick reply. Yes, I'm using language transforms to build a multi-language installer and using a bootstrapper at runtime to install the right language depending on the locale. Could you elaborate a little more on what the custom actions would do in a multi-language patch? In my case, there would be updated localized strings and updated locale-dependent data in the patch. I read another of your posts: WiX: Patching something you didnt build with WiX using WiX. If I understand correctly, torch can take msi as input for base product and upgraded product, but the msi must be admin image where locale has been chosen. My qeustion here is, if the input msi has transforms embedded, would torch be able to accept the transforms? In this case, locale is not chosen yet and thus no admin image is available to torch. Recently (in last couple days) in the WiX-user maillist 'General discussion for Windows Installer XML toolset', some people asks 'Passing TRANSFORMS into MSI patch'. I would have the same question except that I intend to pass language transforms into MSI patch. Would you give us some insights on that subject as well? Thank you very much for your time and help! Harry

    I've done a bit of searching and I still can't find the solution for this:  when I try to change the text file in the example to an executable, the executable does not get updated when I run the patch.  Do I have to set some attributes and/or compile the files differently so that executables get patched properly?

  • Anonymous

    Is there a difference between the executables? If there is no difference, it will be dropped from the patch.

    If you want to include all the changes between your target and upgrade builds, you can either have no patch families, or patch families with no contents. The absence of any patch family contents tells the patch build system to include everything.

Then altered fixed.wxs as follows: <!--------------- Fixed.wxs - Start ---------------!> <?xml version="1.0" encoding="UTF-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">    <Product    Id="48C49ACE-90CF-4161-9C6E-9162115A54DD"                Name="WiX Patch Example Product"                Language="1033"                Version="1.0.1"                Manufacturer="Dynamo Corporation"                UpgradeCode="48C49ACE-90CF-4161-9C6E-9162115A54DD">        <Package    Compressed="yes"                    Description="Installs a file that will be patched."                    Comments="This Product does not install any executables"                    InstallerVersion="200"                    InstallScope="perMachine"                        />        <Media Id="1" Cabinet="product.cab" EmbedCab="yes" />        <FeatureRef Id="SampleProductFeature"/>    </Product>    <Fragment>        <Feature Id="SampleProductFeature" Title="Sample Product Feature" Level="1">            <ComponentRef Id="SampleComponent" />            <ComponentRef Id="Sample2" />        </Feature>    </Fragment>    <Fragment>        <DirectoryRef Id="SampleProductFolder">            <Component Id="SampleComponent" Guid="{C28843DA-EF08-41CC-BA75-D2B99D8A1983}" DiskId="1">                <File Id="SampleFile" Name="Sample.txt" Source="$(var.ProjectDir)..FilesPatch1Readme.txt"/>            </Component>        </DirectoryRef>    </Fragment>    <Fragment>        <DirectoryRef Id="SampleProductFolder">            <Component Id="Sample2" Guid="{923248E0-B4B5-4c8c-B343-420EE64CEF88}" DiskId="1">                <File Id="SampleFile2" Name="Sample2.txt" Source="$(var.ProjectDir)..FilesPatch1Readme2.txt" />            </Component>        </DirectoryRef>    </Fragment>    <Fragment>        <Directory Id="TARGETDIR" Name="SourceDir">            <Directory Id="ProgramFilesFolder" Name="PFiles">                <Directory Id="SampleProductFolder" Name="Patch Sample Directory">                </Directory>            </Directory>        </Directory>    </Fragment> </Wix> <!--------------- Fixed.wxs - End ---------------!> Build the fixed.wxs project in the normal way to get the fixed.wixpdb I then created a patch.wxs to create the MSP: <!--------------- Patch.wxs - Start ---------------!> <?xml version="1.0" encoding="UTF-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">    <Patch        AllowRemoval="yes"        Manufacturer="Dynamo Corp"        MoreInfoURL="http://www.dynamocorp.com/"        DisplayName="Sample Patch"        Description="Small Update Patch"        Classification="Update"        OptimizedInstallMode="yes"        >        <Media Id="5000" Cabinet="RTM.cab">            <PatchBaseline Id="RTM"/>        </Media>        <PatchFamily    Id='SamplePatchFamily'                        ProductCode="48C49ACE-90CF-4161-9C6E-9162115A54DD"                        Version='1.0.1'                        Supersede='no'>            <ComponentRef Id="SampleComponent"/>        </PatchFamily>    </Patch> </Wix> <!--------------- Patch.wxs - End ---------------!> Then ran the following commands: torch -p -xi install.wixpdb fixed.wixpdb -out Diff.wixmst candle.exe patch.wxs -out patch.wixobj light.exe patch.wixobj -out patch.wixmsp pyro.exe patch.wixmsp -out patch.msp -t RTM Diff.wixmst This build the MSP. I installed the installed the original msi (install.msi), then installed ran the patch.msp.  It managed to upgrade the txt files, but to my surprise it upgraded both txt files!! I had only specified in the Patch.wxs the component 'SampleComponent' to be included in the patch..  But seemed to have updated everything.. I check this using Orca and it appeared that the it was updating all components. Is there a know problem or am I doing something wrong ? Thanks whgibbo

    From a quick look, everything appears to be correct and the behavior you are expecting should be the result. I can take a look at this on Thursday night when I work on WiX if you haven't figured it out yet.

    Hey Peter I think you missed somthing please take look here he is using  Readme2.txt from patch1 folder & earlier in base version he is using org folder <File Id="SampleFile2" Name="Sample2.txt" Source="$(var.ProjectDir)..FilesPatch1Readme2.txt" /> Second file may get updated because of that.. I am not sure

    Just wondering if somebody could help on my below requirement. Is there any way of achieving this through patching. When you install the MSI in a fresh/new server, it should install all the files which are packed inside the MSI. When you install the MSI in an existing server, only the changed set of files needs to be deployed and not all the files. Thanks in advance.

    Hi Peter, Thank you for the nice and useful articles. Wix rocks, even though the documentation is scarce and we struggle sometimes with errors and problems. I have installed Wix 3.6 and I'm trying to create a patch using your guidelines. It seems that something is wrong, because I keep getting an error saying: Patch.wxs(12) : warning PYRO1079 : The cabinet 'RTM.cab' does not contain any files.  If this installation contains no files, this warning can likely be safely ignored.  Otherwise, please add files to the cabinet or remove it. diff.wixmst : error PYRO0227 : The transform being built did not contain any differences so it could not be created. I'm trying to create the patch for a web application and I have modified two files: one dll (changed the version from 1.0.0.0 to 1.0.0.1) and one css file. I have checked the new MSI using ORCA and everything looks alright, the dll version is updated and the css is modified. It also works if I install the new MSI. However, I cannot create the patch. This guy is getting the same error: sourceforge.net/.../message.php Is there a known issue with creating patches in 3.6? Thanks, Dan

    It may sound stupid but I am confused with these samples. Is there a straight forward tutorial which tells me how to create a patch (minor update) installer in Visual Studio 2010? The steps would be    a. Create New project -> Select Windows Installer XML->Setup Project.    b. Write the installer for a Sample Product which has 2 files. You right click and hit build and it creates the     .msi.    c. Now create a "Patch.wxs" in the same solution (?) for the minor update for the Sample Product which replaces only one of the 2 files installed.    d. What should be the tags for GUID, Family DiskID etc.?    e. Should it be separate VS solution?    f. Why does it not build and create a patch ".msi"? Any help is greatly appreciated!! Thanks, Aseem Chiplonkar
