App-V 5 Application Launch Failure - 0x3E501405-0x90001

  • Article

Hi all,

Welcome to the Virtual Shell blog, my name is David Falkus and I'm a Senior Premier Field Engineer based in the UK who specializes in Application Virtualization, PowerShell and the Windows Shell.

In this post we're going to look at the following App-V error "The Application failed to launch - 0x3E501405-0x00090001". I'm sure many of you have seen this before when you launch an application, the first thought is what's causing it?

LaunchFailure

The first point of call is looking in the Event Log for App-V 5 and what you find in the Admin event log are the following messages, firstly "Content required by an application could not be retrieved from the network."

EventLog_Message1

And then "Process failed to start due to the Virtual Filesystem subsystem failure." which has the error code from the initial message.

EventLog_Message2

The first thing you need to do is translate the message into a meaningful format to start the debugging:

Code: 3E501405-00090001
Result: Error
Type: App-V
Module: Shared Components (05)
HRESULT: 0x00090001
Message: ERROR_INVALID_FUNCTION

If you want to debug a HRESULT you can use a tool which you can download from Microsoft which is ERR.EXE (Note: The link references Exchange 2007 but it can be used with any HRESULT returned from Windows)

https://www.microsoft.com/en-us/download/details.aspx?id=985

The debug of the App-V error code doesn't really give anything away but if you look at first message it states the following:

"failed with error Not found (404)..  "

The App-V 5 client is returning a ERROR_INVALID_FUNCTION which can also be seen on MSDN - https://msdn.microsoft.com/en-us/library/cc231199.aspx and its correct the function to check the package path from the client fails so from here we need to test if the path to the package is valid and for that we can use a PowerShell command Test-Path - https://technet.microsoft.com/en-us/library/hh849776.aspx.

test-pathXML

The above screenshot has returned "False" which is the cause of the error, if the App-V Client can't find the path to the package and its not fully mounted then this error will occur, once the path is valid the application launches as expected.

Hope this helps in understanding this App-V Error code.
