Can't Sign Into iTunes Account (Error Code: 0x80090302 )

I also have this problem starting from yesterday. iTunes 12.6.2.20 on Windows 7 x64 can't connect to iTunes Store with error 0x80090302 :-(

Same problem. I think that (maybe) the culprit is the last Windows 10 updates on my PC. I have received them today.

iTunes 12.6.3.6

Apple thoughtfully dropped support for Windows Vista on May 25th with no prior warning via email. I've lost my account balance thanks to this, and now I buy my music elsewhere, thanks Apple.

Same Problem, different operating systems (Win7, Win10)

I also have this problem starting from today. iTunes 12.6.2.20 on Windows 7 x64 can't connect to iTunes Store with error 0x80090302. Any solution!

Had I know this was going to happen, I would have used up my account balance.

At least three replies have said how to fix it, including the one immediately before yours 😉.

Microsoft offered a free upgrade. I guess you missed it. And the discussion is about iTunes and not Windows, so thanks for playing.

Thanks for the info. I am curious, why Apple did not automatically updated my old 12.1.3 to the new one, even told me, that "its the most resent version", when i tried to update it...

I can now login to the store in iTunes 11.2.2.3. Apple must have turned this back on, at least temporarily.

Holy crap! you're right. 🙂

It looks like a Chernobyl baby, and it's disturbing.

The fix lies in completely removing iTunes (along with all registry files) from your Windows PC and then re-installing iTunes.
