FAQ
Error 0xC004F074
Cannot reach the activation channel. Please check your network connection.
Error 0xC004F069
The key does not match your system edition. Run slmgr /dlv to check the version, then select the matching edition.
Office will not activate
Office uses ospp.vbs instead of slmgr. The generated command switches automatically once you pick the Office category.
Validity and renewal
Activation is valid for 180 days. The client renews automatically and cannot be renewed manually; each renewal resets the period to 180 days.
