maybe you have installed 2.0 and 2.1 at the same time and in the startmenu you see a link to the version for 2.0?
For certain upgrades uninstalling the old version first was recommended, see https://apps.ankiweb.net/
Recent Anki versions should be in C:\Program Files\Anki whereas old versions were in “C:\Program Files (x86)\Anki`. Check if you find the latter folder in your windows explorer.
Then I’d try to delete this and the start menu entry: From the control panel I’d try to uninstall all anki verions. if you still have a start menu entry for anki I’d manually remove it and manually rename the “C:\Program Files (x86)\Anki` to something like “Anki_”. Then I’d restart and reinstall Anki 2.1. Then hopefully you get a new start menu entry that points to 2.1
Before you try this:
- make sure to have a backup.
- wait two or three days if another user finds a fatal flaw in my idea or has a better one.
