Frequently Asked Questions
Why does Office 2013 keep asking for my product key every time I open it?
This typically happens due to corrupted licensing files, interference from overly strict antivirus software, or compatibility issues with newer operating systems like Windows 11 preventing the activation status from being securely saved to your computer's registry.
Can I transfer Office 2013 Professional Plus to a new Windows 11 computer?
It depends on how the license was purchased. Retail licenses can generally be transferred to a new device. However, the Professional Plus edition is often a volume license provided by an employer or school, which may be tied to the original hardware and non-transferable.
Should I manually delete Office registry keys to fix the activation loop?
No, manually editing or deleting registry entries is risky and can cause severe system instability. It is highly recommended to use the official Microsoft Support and Recovery Assistant (SaRA) to handle registry and licensing repairs automatically and safely.
