I was trying to install the Citrix ICA client on a new WS2008 R2 server I had built for home. The ICA client is a .msi file and everytime I tried to install it I got the message “The system administrator has set policies to prevent this installation”
I am the system administrator with Domain Admin priviledges, and I haven’t set any policies so I couldn’t understand why I was hitting this issue especially since my previous server was a WS2008 R2 server as well I and installed the same programs on it without issue.
Anyway thanks to other contributors on the web the answer turned out to be a DisableMSI reg key I needed.
DisableMSI set to 0
The most helpful site for me was Rick Mitchell’s Stuff at:
The issue can happen for any .msi file you try and install on a Win 2008 R2 server. .EXE install files don’t seem to be a problem.
Other sites suggested adjusting the Enforcement policy under Software Restrictions Policies but this was not the answer for me.
