I had to re-set my personal settings, which included re-install
Outlook. I am trying to install the Personal Folder Backup again, but
get the message that the system dedected an previous version, which I
need to uninstall in add/remove programs first, before the new
version can be installed.
When I got into add/remove programs, it doesn't show the previous
version, and therefore I can't uninstall it.
Any idea how to solve that issue, or where the previous version would
be excatly? Thank you.

You don't state your Outlook version. The following should work for OL
2002/2003.

Open Outlook and click ToolsOptionsOtherAdvanced OptionsCOM Add-Ins.
Click Add. Browse to C:\Program Files\Microsoft Office\Office10\AddIns and
select outbak.dll. Click OK. (Note, the "10" might be "11" for OL 2003.)
