ThinOS 8.6_412 Installation of RTME package

Hello,

I have upgraded some 3040 ThinOS clients to 8.6_412 and trying to install the related RTME package:

"ThinOS 8.6_412 RTME package for Dell Wyse thin clients with ThinOS and Dell Wyse thin clients with PCoIP"

Version 2.8.54007, 8.6_412

The installation fails with the message: download not possible or illegal file.  I have downloaded the file again from the dell website and uploaded it to the WMS. Recreated the policies and jobs but the error stays the same for all clients tested.

Anybody has the same problem or a clue what is going on ?
