Run time error "Could not load file or assembly"

I just purchased the latest version of the ComponentPro.Zip Version 7.1.233 and at run-time, I get the following error with my custom app: "Could not load file or assembly 'ComponentPro.Zip, Version 7.1.40.233, Culture=neutral, PublicKeyToken=0efede2d78b28dff' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference" The compiled samples that come with the ComponentPro.Zip download works just fine. But once I deploy my app, I get the above error once my code calls the assembly. What does it mean by 'manifest'? Any ideas?

Hello, The assembly is compiled for AnyCpu. How did you deploy that app? Could you send us an example to reproduce this issue? It says that you are referrering to the wrong DLL version. The best way is to pull the package from nuget.org and apply your production key, clean & rebuild and deploy again. Let us know if it works.
