We are experiencing several issues with WVD MSIX App Attach.
Locally the MSIX packages work fine but when they are started via Remote App (App Attach) the problems starts.
For some users the applications work well, for some users the explorer opens, some get an AiStub error and by some just nothing happens.
So it is very variable. If we then offer these applications as APP-V, the applications work well. The solution for the AiStub error is to use PsfTooling, we did this but it is still strange that it works for some users.
We see some difference between Advanced Installer and MSIX packaging tool.
Packages that are created with AI doesn't seems to work via Remote App, we look inside the package there is some difference in de folder structure (see screenshot, left is AI)
Can that be the problem?
