Frequently Asked Questions
Can I use the Install ID from the Windows Registry to reinstall Office 2019?
No. The Install ID found in the Windows Registry is used for system identification and activation purposes. It is not the 25-character product key required to activate or reinstall Office.
What if I forgot which Microsoft account is linked to my Office 2019?
Try signing into office.com with all possible personal email addresses you might have used during the purchase. Check the 'Services & subscriptions' section under each account to locate your active Office license.
How do I reinstall Project 2019 if I only have the product key?
If you have a valid product key but no installation disc, go to setup.office.com, sign in with your Microsoft account, enter your 25-character key, and follow the prompts to download the installer.
How do I fix error 43137 in Microsoft Office?
Error 43137 typically points to a corruption in your activation or licensing files. Uninstalling the software completely and then reinstalling it directly from your Microsoft account's 'Services & subscriptions' page usually resolves this issue.
