See the suggested solutions above.
But because this thread is getting long, I’ll summarize –
- Uninstall Anki through your Windows system.
- If anything is still at either of these program locations – Managing Files - Anki Manual – delete those folders.
- If you installed somewhere other than the default location, you can right-click on any shortcut to Anki and “Open file location” (which may be inside “Properties”).
- Your user data is stored separately from the program, so as long as you don’t delete that, your collection will be fine.
- Go to Anki - powerful, intelligent flashcards to download and install the new release.
