Glad to hear it worked out for you. Here's the comments in answer form... The linked SO answer is referring to the system PATH. In Windows 7 you can set it through:
- Right-click on the My Computer icon
- Choose Properties from the context menu
- Click the Advanced tab
- Click the Environment Variables button
- Click on the variable called 'Path' and then click on Edit and enter the path for cl.exe
As for choosing the correct cl.exe, if you're on a non-itanium intel processor (i.e. x86) you'll want x86_amd64
