Hi every one

I create a setup file form my application, then I had to make some changes and recreate the same setup file but I couldn’t install it until I uninstall the previous version manually, is there a way to make my new setup file uninstall the previous version automatically

Hello,
I've had had the same problem a couple of months ago. In my situation I used the same product-code for both install packages. So I got always a message like "the product you would like to install is alrady installed. Cancel installation.".

By changing the product-code I've fixed the problem.

Note: Don't touch your upgrade code. Otherwise windows installer will not support upgrades for your "old" procuct version.

Hope that helps

Kind regards
Andreas
