Office 365 Activation TPM error 80090034

This was a royal pain to solve!

1. Is your BIOS up to date? Like really really up to date? I had to use the latest BETA version, not the latest STABLE version.
   • Remember to DECRYPT BEFORE bios updates or have your recovery key handy.
2. tpm.msc
   • Does the system see the TPM? Yes/No, solve this.
3. Can you encrypt with bitlocker? Yes/No, solve this next. Mine worked.
4. sfc /scannow (does this finish or pass? Mine hung at 56%)
5. chkdsk /r /f c: (does this finish? Mine did.)
6. sfc /scannow (after chkdsk, does this now finish? Now it passed.)
7. Is Windows completely up to date? Check over and over until ALL windows updates are installed. All optional updates too!
8. Have you removed ALL office accounts from Windows?
   • Settings > Add, edit, delete users > Email & Accounts
   • Launch WORD > (Upper right corner, your username and all others) Sign Out
   • Settings > Add, edit, delete users > Access Work or School
     • “Unlink” the account.
9. Have you turned off Windows Firewall (or other providers’ firewalls)?
10. Have you added this registry entry? Mine did not exist.
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb
    • DWord: ProtectionPolicy=1 (create it if it doesn’t exist)
11. Have you removed Office completely? Look for Office folders all over your PC:
    • C:\Program Files\Microsoft\Office
    • C:\Program Files (x86)\Microsoft\Office
    • C:\ProgramData\Microsoft\Office
    • C:\ProgramData\Office
    • C:\Users\[username]\AppData\Local, LocalLow, and Roaming\Microsoft\Office
    • I went a step further and also deleted any “Word”, “Outlook”, “Excel”, “Powerpoint”, etc. that I found.
      HINT: Don’t empty your recycle bin in case you need this data later, like to recover/import outlook OST or PST data files.
12. Did you delete the registry entries for old/stale MS Office versions too? Google this list if needed.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppVISV
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office
    • HKEY_LOCAL_MACHINE\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft Office
    • HKEY_CURRENT_USER\Software\Microsoft\Office
13. After all this, install office365 (don’t sign in/activate yet).
14. Next update office365 (prior to activation)
    • Word > File > Account > Office Updates, Update Options > Update Now
15. Reboot after the updates complete.
16. Launch Word.
17. Sign in / Activate. I got the following error:
    • Your organization has deleted your device (no, actually we didn’t).
    • Error 700003
    • Only clickable button was “continue”
    • …and it activated!!! No account errors anymore!
18. Remember to turn your firewall back on! Cheers.

Hope this helps someone, it’s most likely not your TPM after all.
What a nightmare!

UPDATE: Had another computer with the same error. This one was getting hung up on the fact that a 32bit version of Microsoft Office Single Image 2010 was installed. Dug deep into the bowels of the computer to find these files and delete them.

C:\Windows\Installers\{907… [big long number here]

This folder had a bunch of office 2010 exe files in it. Deleted that and the one after it. Then searched through the registry for every instance of “Single Image” and “Office 2010” and deleted those keys.
