Could not load file or assembly CabLib or one of its dependencies

When using WSPBuilder from command line you may get the following error: “Could not load file or assembly ‘CabLib, Version=, Culture=neutral, PublicKeyToken=5c838b77b53f84a0’ or one of its dependencies. An attempt was made toload a program with an incorrect format.” This error occurs if there is something wrong with CabLib.dll or if CabLib.dll doesn’t exist in same folder with WSPBuilder.

Steps to fix:

  1. Make sure CabLib.dll is in same folder with WSPBuilder.exe
  2. Make sure you have correct version of CabLib.dll (32bit or 64bit)

On 64bit virtual server I replaced the old CabLib.dll with 64bit version and I got this error solved.
