So the App-V client has some hidden registry keys to disable the different subsystems globally and this can be very useful.
The old recipe for SSMS 17.x was a nice success for me with about 1000 hits. Especially the comments were enlightening. The licensing problem could be solved with a simple registration key. With 18.5 there is nothing more to do here.
Again and again we had to find out that sometimes App-V shortcuts in the user profile or even globally on the back. This can happen for various reasons. In particular, after a missing unpublishing for a user even if the package no longer exists. For nonpersistent VDI or Terminal Server this is no problem in the global context under C:\ProgramData\Microsoft\Windows\Start Menu\Programs, because the systems are always in their original state after a reboot.For user profiles, however, this is a problem.
Since I have a little more time right now, I finally get to publish the script I created a long time ago for this problem.
A few weeks ago, one of our customers experienced the problem that some App-V applications were not started until the second start. This seemed to be caused by the registry staging of the App-V application. With App-V Registry Staging, data from the application is copied to the following area of the registry when the application (Publish AppVClientPackage) is released.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppV\Client\Packages\<PACKAGEID>\Versions\VERSIONID\REGISTRY
When the action is complete, an empty key RegistryStagingFinished is generated.
It's been a while since I've published anything here. I often don't have the time to do some really cool things in the basement. Only some time ago I played with the App-V Eventlog and found out which App-V events there are at all. That's interesting because there are news that nobody actually knows about. The messages are no real help for errors. I recommend rather the website http://app-v.de/html/app-v_5_error_codes.html . Still, maybe you can do something with it. By the way, there are many more App_V log providers. Please ask if you need one
