Setup and deployment

[JuggaloBrotha]

I've never have any problems with making installers in VS 2005 & 2008 but in VS 2010 I'm noticing that no matter how I configure it, it will not install the new version on top of the current version of my application. I even created a new test app and am able to duplicate it, the new version does not remove the old version nor does it install the new version in any way.
I'm running this on Win7 Ultimate x64, the testapp and installer are targeting x86.
Installer v1.0 installs app v1.0 just fine.
Installer v2.0 installs app v2.0 just fine if app 1.0 is not installed already.
Installer v2.0 shows the copy file progress bar and says it completes, when I run the app it is v1.0 still.

Anyone else have this experience?
I've done this in VS2005 and 2008 for many apps and have never had this happen, it's definitely a VS 2010 issue.

Are you changing the ProductCode of the Setup project?

Yes
I also have "RemovePreviousVersions" set to True and I tried it both being backward compatible GUID with VS 2008 generation being set to true and tried it being set to false.
For whatever reason, the 2nd installer does not remove the first installation and does not overwrite the first installation's files.

I'm in the process of setting up an XP VM to see if this problem is just a Win7 issue or not too.
