Completely Uninstall Office and Reinstall the Correct Version
Use the official Microsoft Support and Recovery Assistant to completely clear the unexpected 32-bit installation, allowing the correct 64-bit version to be installed and activated.
A standard uninstallation from the Control Panel may leave behind registry keys or licensing files that cause the product key to fail or force the 32-bit version to persist. Using the official removal tool ensures a clean slate.
Download and run the Microsoft Support and Recovery Assistant (SaRA) or the official Office uninstall support tool from the Microsoft website.
Follow the on-screen prompts in the tool, select the Office Professional Plus 2019 installation, and allow the software to completely remove it from your system.
Once the removal process is complete, restart your computer to apply the changes and clear any locked temporary files.
Sign in to your Microsoft account's 'Services & subscriptions' page, locate your Office 2019 purchase, select 'Other options', and explicitly choose the 64-bit installation media to download and install.
Launch Word or Excel, and sign in with your Microsoft account or enter your 25-character product key when prompted to successfully activate the software.

Frequently Asked Questions
Will uninstalling Office 2019 delete my personal Word and Excel files?
No, uninstalling Microsoft Office only removes the application files. Your personal documents, spreadsheets, and presentations remain safely on your computer's hard drive.
How do I ensure I download the 64-bit version of Office 2019?
When downloading Office from your Microsoft account's 'Services & subscriptions' page, do not click the default download button immediately. Instead, select 'Other options' or 'Advanced' next to it, and explicitly choose the 64-bit version from the dropdown menu before downloading the installer.
Why does my Office 2019 product key fail after a wrong installation?
If a 32-bit version was installed over or alongside a 64-bit version, licensing conflicts can occur in the system registry. A clean uninstallation using the official Microsoft Support and Recovery Assistant clears these corrupted licensing files, allowing your product key to validate correctly during the new installation.
Where can I find my 25-character Office product key?
Your product key is typically found on the physical card inside the packaging if bought in a retail store, or in the confirmation email if purchased digitally. If your license is linked digitally, you will not need a key; simply sign in with the associated Microsoft account under the 'Services & subscriptions' section.
