Hello,

I’m getting what looks like a build error when trying to run my circuit simulation in WSM. The error is,

“LINK : fatal error LNK1104: cannot open file ‘libcpmt.lib’  
NMAKE : fatal error U1077: ‘“C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\BIN\cl.EXE”’ : return code ‘0x2’  
Stop.”

So does anyone have any idea how to remedy this?

Thanks.

I installed the most recent Visual Studio Community and the problem want away. So, never mind! 🙂
