Creative Cloud 5.7.0.1307 not updating Windows 10

[Bartdenood]

Last week I had some issues updating CC. After being in touch with Adobe support I installed an older version of CC that worked. The support rep said it had to to with the new installer not working nice with user profiles that are on a network drive. And that's my situation here. However, downgrading to an older version seemed to do the trick. Fine. Suddenly I get an update prompt from CC. I can't do anything besides clicking "update". So now I'm back at where I started last week.

CC is now updated to  5.7.0.1307. Again it prompts me for an update. When I click "update", I get a message saying "There are problems updating Creative Cloud. Error code 304".

I can't update apps, I can't update CC, I can't install new apps, I can't enable/disable fonts, nothing.

I tried every possible solution I could find (and I found a lot), but nothing seems to work. It all worked fine before 5.7.0.1307...

If you have some suggestions - please let me know...

Win: Ctrl + Alt + R
Mac: Cmd + Opt + R
