So, are you seeing this error on your test VM or are you seeing it on an SCCM managed client?
Does the App-V log file (sftlog.txt, usualy in an subfolder of %programdata%) give some more information?
Does it happen to just one application or to all?
How do yopu deploy the package? locally executing the MSI manually, deploy it using SCCM as a 'normal' application or deploy it using SCCM as a 'virtual' application.
The format of the error message indicates that you are using App-V 4.x; what version fo ConfigMgr?
