App-V Sync not working if Device Guard is enabled

[SGERN]

Hi there,

In September 2017 Rollup there where some changes to Device Guard which increase teh Overall security of your System. As a result the way how our SyncAppVPublishingServer.exe does it work no longer works.

As a result you see that the Sync Process is crashing - no further notice (except that you don't have App-V Apps). Only if we cut the Machine from Network we get something in the Logs which Points into this direction:



With that Info we could identify what is happening. Finally we have a Fix Ready for the upcoming Rollups.

Thanks
