I’ve installed the Windows Management Framework 3.0 CTP, which includes PowerShell 3.0.

But now I can’t figure out how to launch a PowerShell 3.0 shell. I don’t see a new PowerShell installation folder with a powershell.exe to execute.

Any help much appreciated!

Once you have installed the CTP, when you run Powershell, it does run the v3.0.

You can do $PSVersionTable to verify.

If you want to run the v2.0 engine, you can do powershell -version 2.0

Note that Powershell, as was the case with v2.0, still installs onto the v1.0 folder.
