Bug Description

Currently the new installer for 2.1 pops up a generic warning saying to uninstall old versions of Mixxx if they are detected then rerun the installer. If possible, the old uninstaller should be run automatically. Failing that, the warning should provide explicit step-by-step instructions to uninstall the old version for every supported version of Windows.

Changed in mixxx:

status: New → Confirmed
importance: Undecided → High
milestone: none → 2.1.0

I think a found a way to do it with vbs scripting. I should be able to open a PR in the next few days.

After some more hours of debugging, headache and swearing, I came to the conclusion that this is impossible.

you have to add lots of dirty hacks and auditioning dirty hacks leads to ... nothing good.

thus, WONTFIX.

Okay, thank you very much for your efforts dealing with our ugly Windows issues! I'll add some links to the release announcements to step-by-step guides for uninstalling programs on different versions of Windows.

I ran into this today when installing Mixxx 2.1.5 on a machine that had Mixxx 2.2.0 beta installed and was pretty peeved that I had to open Control Panel -> Applications -> Run the Mixxx installer manually.

It would also be nice if we could give the user a nice comforting message that "Don't worry all your data is safe even though we're uninstalling Mixxx 2.x".

Sebastien, were you WontFixing the ability for WiX to run the NSIS uninstaller? Or is it just as hard for WiX to run the uninstaller of a WiX-produced installation?

"Confirmed" is kind of weak, because what I observed was WiX wouldn't run the uninstaller on 2.2.0 beta while installing 2.1.5. JosepMa reports that upgrading works fine (uninstalls the old version first, e.g. from 2.1.4 -> 2.1.5).
