Fix For Office 365 / App-V Interaction

In my previous post on this subject, I came to the conclusion that Office 365 apps just wouldn’t run in an App-V virtual environment. However there is a fix for this that can be applied to the client registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClickToRun\OverRide]
"AllowJitvInAppvVirtualizedProcess"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ClickToRun\OverRide]
"AllowJitvInAppvVirtualizedProcess"=dword:00000001

Now, the only official mention of this key anywhere online used to be in this knowledge base article:

https://support.microsoft.com/en-us/help/3159732/-click-to-join-fails-to-invoke-skype-for-business-on-computers-that-us

Even a Google search for ‘AllowJitvInAppvVirtualizedProcess’ turns up this article, however all reference to it has now been removed. What this means in terms of support I have no idea, so this setting should be added at your own risk; however I have found it to fix multiple issues including:

  • Creating shortcuts to Excel as a way to sequence Excel add-ins
  • Pasting Visio objects from virtualised Visio into Office 365 Word

I have so far not seen any negative effects from using this setting and am recommending that people use it, with the disclaimer that anybody should contact Microsoft support before doing so!
