Flash Player 19.0.0.207 can not be installet on XenApp virtualized environment

Hello together

Environment:

Windows Server 2008 R2

XenaApp Server: Citrix 6.5 - PDI

Deployment:

SCUP -> SCCM 2012

the last installed version of Flash Player: 18.0.0.232

Problem description:

- the previous version 19.0.0.195 could not be installed due to MSI

- therefore we have disabled the usage of Flash Player for security reason

- yesterday I've published the new Flash Player Catalog over SCUP and deployed it over SCCM 2012 to the FAT/VDI and PDI (w2k8 R2 XenApp serevers) Clients

- the FAT Clients and VDI's were updates successfully - OK

- on the xenapp servers happens nothing - as if nothing was deployed.

- In control panel is still 18.0.0.232 version shown.
