I love PowerShell. Every so often - tongue-in-cheek - Microsoft produces one very funky piece of technology. PowerShell is one such bit of goodness.
Well, now that I've installed 64-bit Vista on my Dell XPS I've noticed little things here and there that don't work like I expect. Most cases there's a good security reason. But sometimes it just that programs don't install properly.
PowerShell Community Extensions (PSCX) is one such beasty. There's a problem with the installer not configuring all the 64-bit stuff.
Luckily there's a quick solution.
Run this command:
C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe "C:\Program Files (x86)\PowerShell Community Extensions\pscx.dll"

Also, don't forget to set Remote Signing in both the 32- and 64-bit PowerShell interfaces.
