I have 150 Windows 7 x64 sp1 machines to deploy to with SCCM CB and can not get the SolidWorks Admin image to install. Here is the log entry of the error. I have tried numerous versions of .NET and numerous Admin Image builds with different installation switches, but there seems to be nothing that works. How can I fix this for installation to 150 machines? The .NET  Framework Repair Tool idea is not an option for 150 machines.
