Visual Studio 2013 app on Server 2003

I developed an app (vb.net) that will run on a Windows 2003 server, but it doesn't run.

It says the application is not a valid 32 bit application.

I've made sure it was a 32bit application (at least I think so) so what else am I missing?

Right click on the project
Select properties
On the build page
Under Platform make sure it says Any CPU (or at least x86)

I would also check that the server has the right version of .NET installed

It turns out it was a couple of things...  first off the server was 2003 which doesn't support .net past 4 and then my IT dept. didn't want to upgrade so I had to downgrade to 3.5 which made my Telerik controls incompatible so I had to remove them.

Sigh... at least it's working, thank you for getting me in the right direction.

Merry Christmas
