I'm trying to get better at using PowerShell, and I've seen that you can get a nice GUI interface using PowerShell ISE. On my Windows 7 machine, when I click the Start menu and then start typing "PowerShell ISE" (without the double quotes) I see there's a 32-bit version and a 64-bit version. Cool, and all that, but which "should" I use?
Basically, use the 64 bit version unless you are interacting with software or cmdlets that only work with the 32 bit version of PowerShell.
Doctor Who :
I had the same issue but succeed with the below commands a while back.
if you have errors in the scripts try to set privileges
Set-ExecutionPolicy Unrestricted -Scope CurrentUser
