Installation on W2012Terminalserver failed due

  • Hello,

    i wanted to install the Deskapp on an W2012Terminal server. My problem is, that i couldn’t do it.

    I got this error:
    Is not permitted due to an error in the processing of the Software Restrictions policy. The object is not trustworthy
    (In german: Die Installation von C:\Users\Administrator\Desktop\kopano-deskapp-1.2.38-x64.msi ist aufgrund eines Fehlers in der Verarbeitung der Richtlinie für Softwareeinschränkungen nicht zugelassen. Das Objekt ist nicht vertrauenswürdig)

    i haven’t got this error bevor and google hasn’t helped.

    There is no Goup policy that restrict softwareinstallation.

    I found many tips about Windows XP and Server 2003, but no help for W2012R2…

    Thanks for help.


  • Hello @volkergrabbe,

    silly question but did you use

    change user /install

    or the integrated installer from w2012 TS? (btw withour R2?)

    and please check if the *.msi-file has no flag set to unsave (right-click -> properties -> “Die Datei stammt von einem anderen Computer. Der Zugrioff wurde aus Sicherheitsgründen eventuell blockiert” -> click “allow” or “Zulassen” )
    The last one got me some days to install exchange-Server update :)
