Well,

I have installed SolidWorks 2014 SP1.0 on my laptop (Windows 7-64 bit) before, uninstalled it and reinstalled it again, when suddenly, it comes to an error message 'The Installation Manager failed to register gdtanalysis.net.dll  C;\Windows\Microsoft.NET\Framework64\v4.0.30319\regasm.exe /silent /codebase "C:\Program Files\SolidWorks Corp\SolidWorks\gdtanalysis.net.dll" returrned to 0x64'.

I already look up at many issues according this, and I can't find a specific matter about this. And yes, I already turn off UAC and run the installation as administrator, and nothing works. Please can somebody help with it? I plan to reinstall my windows 7 if this error still occurs. So, I really appreciate if somebody can help me fix this

Best Regards,

Philip
