Citrix PS 4.5 Enterprise — Error 10001
August 24th, 2007
It turns out my encounter with this error was due to a “bad” install of .NET 2.0. I could not perform a security update of .NET 2.0. I ignored the security update error and proceeded to perform the Citrix PS 4.5 install. Near the end of the Citrix server component installation, the installer began uninstalling all of the PS 4.5 server software components. The Citrix error returned after the uninstall was 10001.
In my earlier blog post I described how I uninstalled and reinstalled .NET 2.0 (a requirement for PS 4.5). After I reinstalled and patched .NET 2.0 I was able to perform a satisfactory PS 4.5 server installation.

I ran into the same thing. PS 4.5 on Server 2003 Enterprise. I had a company packaged version of .NET 2.0. Removing it and letting PS 4.5 install the version of .NET 2.0 that ships with it resolved the issue.
