LINK : fatal error LNK1171: unable to load mspdb140.dll (error

Error: `VS\VC\Tools\MSVC\14.10.25017\bin\HostX86\x64\link.exe` 
failed with status: 1171

I'm pretty sure that it is using the x64 mspdb140.dll because 
procmon says it is

VS\VC\Tools\MSVC\14.10.25017\bin\HostX86\x64\mspdb140.dll

But maybe this isn't the correct one?

It seems to be looking in a bunch of dir's, including

ldc2\bin\mspdb140.dll

and the windows kit's, sdk, and VC dir, it finds them but I guess 
they are all x86.

It looks at

Windows Kits\8.1\bin\x64\mspdb140.dll

and just about every dir in the %path%... it finds many 
versions(x86 and x64) but never is satisfied.

and the dll is there but it doesn't use it.


Why does it need the pdb anyways? I thought that was for 
debugging?

The problem is that it seems to need the x86 version even when 
compiling for x64. When using x64, the paths are switched to x64 
dlls and hence it fails to load it. I stuck the x86 dll in some 
path that it was looking in and it worked, but didn't work when I 
stuck the x64 dll in the same location overwriting the x86 
version.
