Problem with Deployment, Win Installer, Setup

[HamCoder]

I started with a solution with two projects. 1=VAQSO (the true project) and 2=VAQSO_Setup (the deployment project). It took a while to get the deployment project correct, but help from Code Project finally got it working. By the time the production cycle finished, VAQSO was at release 06.12.03 Next I cloned the solution. I copied the entire solution directory to a new directory and changed all the code so that VA became WV. Now I have WVQSO and WVQSO_Setup. Both programs and both installers run well, with one exception. Both programs will not install on the same PC. If VAQSO is installed on a PC, then WVQSO will not install. I get an error message about a prior version existing. If I uninstall VAQSO, the WVQSO will install without error. Obviously, I've still got a VA reference in the WV clone. How do I find it? I've run a scan on all the text files in the solution and nothing shows up. Thanks for the help. --HamCoder

Change the product Guid in the installer setup (they obviously have the same guid - hence MSI thinks they are the same thing) the name portion is for humans to understand sorry i cant be more specific but i havnt got VS open in front of me

Thanks. I thought I had checked that. It turned out to be the Upgrade GUID that was identical. Once I had the IDE generate a new one, it worked just fine. --HamCoder
