First, I don't see any matches for "ISE" when I click the start button and type "ISE". I am able to run C:\Windows\System32\WindowsPowerShell\v1.0\powershell_ise.exe and open ISE it seems to be the 64-bit, because I ran the following:
[Environment]::Is64BitProcess
and it showed the response of "True".
How can I run the 32-bit version of Powershell ISE? Where is the .exe for it? It's V 4.0 of Powershell.
