Adobe Air Certificate Problem

Hey,
I just recieved my AIR certificate for my new AIR-app and i instantly ran into errors.

Publishing is just fine, but when i try to install the app it gives me this error:
This application cannot be installed because this installer has been mis-configured. Please contact the application author for assistance.

I’ve googled through possible solutions, but i’ve yet to found someone with a brand new application and certificate who has recieved this error.

I’d greatly appreciate your 2 cents in this matter.
