After installing SharePoint 2010 I was unable to open the SharePoint 2010 Management Shell. As soon as PowerShell ran I got a nice error stating:
Add-PSSnapin : The Windows PowerShell snap-in 'Microsoft.SharePoint.PowerShell'
is not installed on this machine.

I wasn't able to find a solution to the problem on the internet so I'm posing the fix to help save you the time of figuring it out. Here's how to fix this problem with the SharePoint 2010 Management Console:
- Open a command prompt with elevated permissions.
- Browse to C:\Windows\Microsoft.NET\Framework64\v2.0.50727
- Execute the InstallUtil.exe with the following command line parameters:
- InstallUtil /LogToConsole=true C:\Windows\assembly\GAC_MSIL\Microsoft.SharePoint.PowerShell\14.0.0.0__71e9bce111e9429c\Microsoft.SharePoint.Powershell.dll
The cause of the problem is because your missing this registry key and the associated values: HKLM\Software\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.SharePoint.PowerShell. Repairing SharePoint didn't fix this problem, I had to figure it out.
