How do I install Outlook Backup add-in to multiple users on my pc?

[napinski]

When I downloaded the Backup add in I was signed in as administrator and it
was installed on "my" Outlook. My daughters sign in separately and when I go
to install the Backup Add in it tells me that I have to uninstall the version
already installed. How do I get the Backup option available for my daughter
when they sign into the computer under their user names?

Check in Tools>Options....Addins/Coms ensure the Backup Addin is ticked

Have her click Tools>Options>Other>Advanced Options>COM Add-Ins. Click Add.
Browse to C:\Program Files\Microsoft Office\OfficeXX\Addins (where "XX" is
probably either 10 or 11), select outbak.dll, and click OK, then OK, then
OK, then OK. "Backup" should now appear on the File menu, but it may
require stopping and restarting Outlook.
