How to Trick System Center Virtual Machine Manager (SCVMM) Prerequisites Checking

Michael Khanin Michael Khanin Profile: Michael Khanin

One of the software requirements for VMM is Windows PowerShell v1. If we try to install SCVMM Administrator Console, we could get this error in the prerequisites dialog:

System Centercentre Virtual Machine Manager requires Windows PowerShell 1.0.

We can see this error in two situations:

  1. We have not installed PowerShell 1.0.
  2. We have installed another version of PowerShell, let say PowerShell CTP 2.

BTW, we will have the same issue if we try to install Exchange 2007 Admin Tools while having PowerShell CTP 2 installed.

The workaround is very simple.
“Prerequisites Checking” is looking for a registry key named PID. The value for this key should be “89383-100-0001260-04309“.

We can create it manually, create file PSv1.reg. Here is a content of PSv1.reg:

Windows Registry Editor Version 5.00

Import the PSv1.reg, by running it, and ran the SCVMM installation again and the problem will disappear.

Now that the prerequisite phase is complete we can safely remove the created key.
