WSP Builder: ERROR: Could not load file or assembly 'CabLib, Version=6.9.26.0, Culture=neutral, PublicKeyToken=85376ef9a48d191a' or one of its dependencies. An attempt was made to load a program with an incorrect format.

PROBLEM:

I'm running the latest release of WSPBuilder and extnsions for Visual Studio 2008. I installed the MSI. I am running on a Windows Server 2003 system with SharePoint on it.

When I was trying to build the WSP then I was getting below error:

"Could not load file or assembly 'CabLib, Version=6.9.26.0, Culture=neutral, PublicKeyToken=85376ef9a48d191a' or one of its dependencies. An attempt was made to load a program with an incorrect format."

I searched for cablib.dll in the WSPBuilder folder, found two versions of cablib.dll one is marked as x64 and x86.

Solution:

I copied the cablib.dll from the "C:\Program Files\WSPTools\WSPBuilderExtensions\Resources\x86"

directory and paste it in the root "C:\Program Files\WSPTools\WSPBuilderExtensions\"

Then everything works fine.
