I upgraded to windows 10 and have lost my office pro plus 2013

Hi,

Regarding of the issue, please provide us more information to assist you better.

• Which OS you have used before upgrading Windows 10?
• Did the other applications have the same issue? Such as Adobe PDF reader?

As far as I know, Windows 10 provides 3 options about upgrading process.

If we choose "Keep personal files" or "Nothing", the apps will not retain after installation.

===

If you only lost Office 2013 pro plus, this issue might be caused by Office 2013 installation corrupted, and Windows 10 will uninstall it during upgrade process.

I recommend you re-install Office 2013 in Windows 10.

Hope it's helpful.

Regards,
