There is a known issue when you publish an App-V 5.0 SP2 package user-based. The issue will be seen when it’s published to roughly ~250 users. This can be observed in the eventlog:
Part or all packages publish failed.
Please check the error events of ‘Configure/Publish Package’ before this message for the details of the failure.
The issue happens because every user that got the app published has been added to the ACL of the published App-V package below c:\programdata\app-V reaches its limit (~250 entries) and therefore the whole publishing mechanism doesn’t work properly anymore. The reason is the PSAC feature (Package Store Access Control) that is depreciated and won’t exist anymore in App-V 5.0 SP3 that will be released soon. So SP3 will fix the issue. In the meantime, the following workarounds exist:
- Publish the app globally and not user-based
- Delete the cache
- Run a scheduled script that will reset the permissions on the folder
