Ableton Forum

Hi,

Upgrading from Live Lite 10. Live Lite 11 totally fails; says "version already installed" (I have removed version 10).

Tried run-as-admin, no luck.

Re-installing v10 is fine.

Glad I haven't yet paid for the full version!!!!!!!! Get your act together, Ableton. Not impressed.

I assume your PC has Windows 10 as OS?
There is a freeware called CCleaner, there you've got some handy functions.
Try to uninstall Ableton with CCleaner and run the Cleaner as well to get rid of old files...
Maybe it's worth a try.
