Subject: [wix-users] Allow multiple installs of our app on a single system
I have a working installer for our app, coded in WiX. The previous version of our app used a different installation tool.
Now, if we try to install our newest version on a system where the previous version is already installed, an error message appears, requiring the user to uninstall the previous version first.
We would like to eliminate this requirement. We feel it is unnecessary.
Since I didn't put anything explicit in the WiX code to cause this, I'm unsure how to proceed.
Any suggestions? Our installer uses WixUI_Mondo, if that makes a difference...
Thanks for any help you can offer.
