How to change ReSharper unit test architecture to x64?

In VS2012, I resolved a BadImageException from running a unit test by going to: TEST-> TEST SETTINGS -> DEFAULT PROCESSOR ARCHITECTURE -> x64.

Answer 1

My solution is too hacky, but thats the only thing which worked for me

I placed a copy of vstest.executionengine.x86.exe for backup and placed a renamed vstest.executionengine.exe (64bit version) instead of old 32 bit version.
