Cura: 3.1 Clean Install - How to completely remove Any Cura versions from Win10/64

[Thisismydigitalself]

I've reached a point where I need to completely clean my PC from any cura installation ever installed so i can at least run 3.1 version solo. Since i upgraded my 3.0.4 to 3.1 Beta i am wasting more time fiddling with it than working with it and I can't install 3.1 release anymore. for some reason it wont run. i was told this is due to the fact that i installed the Beta version which messed up something _(ValueError: max() arg is an empty sequence)_ .

Please direct me what to backup and how to completely remove any(!) version ever installed, including files, folders, registry, instances, etc.. I want to start off with a clean slate.

These days I can only run 3.1Beta.
3.1 release and 3.0.4 will not run anymore.

I don't know when 3.2 is due. if it was few days away i would have waited but even if it will be out as soon as tomorrow i don't want to upgrade from my currently messed up environment.

Sorry. I just want to go back and enjoy Cura like I used to.
Thank you!

Modern Cura has files in:

• %PROGRAMFILES%\Cura 2.*
• %PROGRAMFILES%\Ultimaker Cura 3.*
• %LOCALAPPDATA%\cura
• %APPDATA%\cura

The files in %LOCALAPPDATA%\cura and %APPDATA%\cura are worth backing up.

Thank you but from experience in my case it was not enough to only uninstall and remove leftover folders. i tried that and still couldn't install 3.1. i guess more is needed. what should i remove from registry?

Cura does not touch the registry

Cura 3.1 release is now running on my PC 👍
These are good news. uninstalling all previous Cura versions and deleting the above mentioned folders did the trick. Now i need to either recreate my profiles and printers and hopefully I am back to square one. I wonder if i need to copy backed up files or to spend the time and created these again from scratch for not bringing in troubles.

What do you say?
Thank you.
