Guidance to upgrade from Windows Vista and to Windows 7 with Visual Studio 2010 Beta 1 Installed

  • [アーティクル]

Hi everyone,

The following will implement preventative measures and will avoid an unusable Visual Studio 2010 on your brand new Windows 7 OS if upgrading from Windows Vista. Please note that .NET Framework 4 Beta 2 has resolved this issue.

If you upgrade to Windows 7 from Windows Vista with the .NET Framework 4 Beta 1 installed, your machine will be in an unreliable state. In this state, Visual Studio 2010, and some managed programs depending on .NET Framework 3.5 or earlier will not work. There is no way to repair a machine that gets into this state. You will need to reinstall Windows 7.

However, uninstalling .NET Framework 4 Beta 1 before upgrading to Windows 7 alleviates this issue and upgrading should work fine. Below are detailed steps to completely remove .NET Framework 4 Beta 1 as well as Visual Studio 2010 Beta 1.

Uninstalling Visual Studio 2010 Beta 1 and .NET Framework 4 Beta 1

d.      The Wizard will load then on the Welcome screen click Next to proceed.

e.     On the Maintenance page click Uninstall and choose OK to completely uninstall.

h.     Repeat this step 2 for each installed version of Visual Studio 2010 Beta 1.

3. Uninstall .NET Framework 4 Beta 1

    I installed VS Team System 2010 Team Suite Beta 1 but now I want to install VS2010 Beta 2. While uninstalling the previous Team suite I get window asking for a CD or the file TFSObjectModel-x86_ENU. But I see this in the Control Panel as being disabled. I cannot find it in my file system.Despite all this the uninstallation seems to be proceeding slowly. How would I uninstall the previous version.
