Done. I added this directory to the "System Variables" section. Then I did Shift + Right mouse click on the source-folder and upon typing : vcvarsall amd64 and still get this message:
"vcvarsall" is not recognized as an internal or external command, operable program or batch file"
.
I've attached the path to where I added it in System Environments. In my case, I defined the Variables as VCVARSALL and its Value is defined as the path: C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC
You need to find "PATH" in the list and add this to the end of it:
;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC
Make sure there is a semi-colon between this entry and the one that you are pasting it behind.
garrd, it worked! . Thank you for your patience and help. I really appreciate this. I was able to make suceesful PGO / MsVS2010 compiles using your switch and methods. My next step is to experiment with other 'switches' you wrote down. Thanks.
