Enterprise Edition 10

Question

I could not get my app to publish in Express Edition 2008 so I down loaded 2010, its imported the solution and now it wont compile.  Any ideas. 

And while Im here - any one know how to get my app published.  I have used both versions and non produce either a stand alond app that will run or an installation process that works.  One verion tried to down load something  -when i told it to run form cd. 

Come on peeps - we  cant all have these problems or no one would ever get anything out there.  I have my appthat I watn to send to some on for testing and I want an installation process - like they would have if it was finished they bought it.

I new to this and if things dont start working I doubt Ill bother to get old at it.
