If you do that, you're applications supposed to run on .NET framework 2, did you do that? with all application references??

Yes I changed the Target Framework to 2.0, and it complies fine.
I also made it so the pre-reqs didn't include the 3.5 Framework.
I thik I also need to change the Framework Destination folder...but I don't know how to do that.

Excuse me, how could you know it's compiling on 3.5 ? did you try to run this application on machine JUST HAS 2.0??
Installation project is 2.0 or 3.5?

The install project was created with the original project because it is a shared add in. When building, I get this in the output section, which is why I believe somewhere it still uses the 3.5 Framework.

Turn it into use 2.0!

I know, how do I do that! That is the question! Haha

I don't have solution else open the downgraded project on VS 2005 then add new project (Setup wizard project) there on it.

But did you answer my questions

Here is my output from compiling a 2.0 project:


You should be OK.

Okay, thanks for the help guys, I will mark as solved and hopefully test it on a 2.0 machine soon. But if it isn't okay I will just create a new project and make sure it starts off using 2.0. But I agree that it should be okay if you get that output as well. Thanks for the help from both of you.
