Windows 2008

(Windows SIM) cannot create catalog files for some images of a different architecture

Today I was attempting to create a sysprep.xml file for Windows 2008. After opening my WIM file in Windows SIM I got the prompt to generate a Catalog file, clicked Yes and then……Error!! What?? Lets try that again….Error!! Whatever, lets try again, Error!! Ok this time I read the error. “System.Reflection.TargetParameterCountException: Parameter count mismatch.” Ummm, what??

After wasting almost 2 hours chasing this error I found this post on the TechNet Forums:

The key information is:

Because of the changes in the servicing stack in Windows Vista with Service Pack 1 (SP1) and Windows Server 2008, Windows System Image Manager (Windows SIM) cannot create catalog files for some Windows images of different architecture types. The following list describes the Image Manager architecture types and catalogs that can be created for each one.

x86 Windows SIM:
Can create catalogs for x86, x64, and Itanium-based Windows images.

x64 Windows SIM:
Can create catalogs only for x64 Windows images.

Itanium-based Windows SIM:
Can create catalogs only for Itanium-based Windows images. 

Please confirm if what version of Windows SIM you are using. I recommend installing x86 Windows SIM.

Hope it helps.
