Crystal Reports VS 2010 - Cannot deploy successfully

26 Views

I've been REALLY struggling to deploy a C# Windows Forms application to another machine that has nothing on it. I feel like I've been going through all of these hoops, and now I'm really stuck.

I get this message:

Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

OK, so I've been told to include <startup useLegacyV2RuntimeActivationPolicy="true"> in my app.config file. Well, that works fine... on my development machine... but it won't work on the deployed machine, with the app.config corrections included.

I've been searching for solutions to these quite frankly weird issues for the last two weeks... there's GOT to be a simpler way.

Thank you for your attention to this matter.
