I have two windows 2008 servers with PDFCreator on them. At some point, whether it was some maintenance or what, PDFCreator stopped working on both. The error I get is this:
Could not load file or assembly 'Interop.PDFCreator, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.
