I had some pain installing Pscx on Windows 7 some of the instructions that came in the download did not work for me and other instructions assumed knowledge. The following explains what worked for me.
My environment details:
OS: Win7 Home Premium 32bit // echo (Get-WmiObject Win32_OperatingSystem).Caption $ENV:Processor_Architecture
Powershell Version: 2.0 // use get-host to check this
1) Ignore the instructions that come with Pscx download
2) After downloading
