Error while trying to run project in VS 2012

Question

I am creating a Windows Form application and trying to debug it. It displays the following error:

error while trying to run project could not load file or assembly or one of its dependencies

I updated and repaired my Visual Studio but error is same. When I go to bin\\debug and try to run .exe it shows this error:

the application was unable to start correctly (0xc000007b)

Answer 1

0xc000007b means STATUS_INVALID_IMAGE_FORMAT, this is an indication that your x86 application tries to load an x64 dll, or that your application target is x64, to check this you can look in the Project properties->Build->Target Platform

If your platform target is not x64 you can check your application dependencies with Dependency Walker and look if one or more of them is a 64 bit dll.
