Outlook Personal Folders backup utility
Have attempted to install the pst backup utility on a computer running Windows XP Pro and Office XP Pro.
When using Outlook I do not see the backup option on the menu.  I have tried installing again as suggested from the Microsoft website, but then am told when I try to install that there is already a copy installed and that I should uninstall it first.  So I go through the Add/Remove programs but it is not listed there to be able to uninstall.  Would like to be able to use this utility to be able to have regular schedule backups.
How can I uninstall to be able to then try and reinstall to hopefully be able to use this utility.
Thanks in advance

Greetings, JPStevie !

   1. To confirm that you try uninstall correctly, In Control Panel, click Add or Remove Programs.
      Note  If you are using Classic view, double-click Add or Remove Programs.
  2. In the list of programs on the Install/Uninstall tab, find Microsoft Outlook Personal Folders Backup, and then select it.
   3. Click Change/Remove.
   4. Confirm that you are certain you want to uninstall this software by clicking Yes.

Best wishes!

With Outlook closed, look for and rename extend.dat file. The file controls the Outlook addins.  Extend.dat is usually installed in C:\Documents and Settings\<user>\Application Data\Microsoft\Outlook folder. It is a hidden file and folder, Go to any folder and select Tools > Folders Options > View. Check "Show hidden files and folders". Click OK.

You may need the Windows Installer Cleanup Utility to remove the Backup tool

Hi, thanks for the response.
The option to uninstall the backup is not displayed in add/ remove programs

Looks like the Backup program did not get completely installed. In the next note, I wrote to rename the extend.dat file and use the Windows Installer cleanup utility.  Follow those instructions.

While I was searching around I came across the following, that I followed and the issue was then resolved:
Found this:

please follow this steps
Re-register the Outbak.dll file. To do this, follow these steps:1. Start Outlook.
2. On the Tools menu, click Options.
3. On the Other tab, click Advanced Options.
4. Click Com Add-Ins, and then click to clear the PF Backup check box.
5. Click OK in each dialog box, and then close Outlook.
6. Click Start, click Run, type the following command, and then click OK:
regsvr32 "c:\program files\microsoft office\office\addins\outbak.dll"
Note This path is the default location. You may have to adjust the path of the Outbak.dll file to match the location that is on your computer.
7. Start Outlook.
8. On the Tools menu, click Options.
9. On the Other tab, click Advanced Options.
10. Click Com Add-Ins, and then click to select the PF Backup check box.
11. Click OK in each dialog box, and then close Outlook.
12. Restart Outlook.
13. On the File menu, click Backup.
The Personal Folders Backup add-in should now run.
It was from someone in the Experts Exchange, but I forgot to copy who the person was, I apologize.
This is was solved my issue, I was leary about using the Microsoft Clean Utility, I did not want it to cause more trouble for me.
What should I do about awarding the points.
Thank you for your responses.

Glad your problem is fixed.  Re-registering Outbak.dll is one way to fix the Backup tool.
