I installed the CR runtime, version 13.0.2.469, on a Win 2003 server. The installation program eneded with a success message. When I try to run my application, I get an error that assembly "CrystalDecisions.CrystalReports.Engine" of the same version cannot be found.

I uninstalled the runtime and reinstalled, this time using Process Monitor to trace. What I found is that there are errors in a number of "Createfile" operations, such as for the engine dll above. The error indicates "Path not found" for "c:\windows\assembly\GAC_MSIL".

I have no experience with the GAC, but when I examine it in Windows Explorer, there is no subfolder named "GAC_MSIL". Since the folder (which I think is a virtual folder) is read-only and cannot be made writeable, even with my Admin ID, what can I do to correct this problem? Also, I don't understand why the installation program for the runtime would have believed it was successful when the core assemblies couldn't be written.
