If you are not able to remove or uninstall an application in Windows XP using the Add/Remove Programs Wizard or Uninstall option you could try the Windows Installer Clean Up Utility. As long as you installed the application using the Windows Installer, this utility will remove all the folders, files, registry keys, and entries from your system.

Here’s how:

1. Download the Windows Installer Clean Up Utility from the Microsoft Download Center.
2. Run the msicuu2.exe file you downloaded to install the Windows Installer Clean Up Utility.
3. Locate and launch the Windows Installer Clean Up Utility on the Start menu.
4. From the Windows Installer Clean Up Utility window, locate the application in the list you want to remove and click the Remove button.
5. Once the application has been removed, click the Exit button to close the utility.

Windows Installer Cleanup

When you use Windows Installer CleanUp Utility, you can perform the following functions:

* Select one or more programs that were installed by Windows Installer from the Windows Installer CleanUp dialog box.

To do this, select the programs that you want in the Installed Products list in the Windows Installer CleanUp dialog box. After you make this selection, the utility removes only Windows Installer configuration information that is related to those programs.

* Remove all Windows Installer information associated with the selected programs. This includes the entries for the programs in the Add Or Remove Programs item in Control Panel. Be aware that only the Installer information for that particular program is removed, not the files.

Windows Installer CleanUp Utility does not perform the following functions:

* Remove Windows Installer
* Remove files of any programs that are installed by Windows Installer, such as Microsoft Office 2003

If you use this utility to remove Windows Installer configuration information for your program and you plan to reinstall the program, you should reinstall the program in the same folder where you originally installed it. This prevents duplication of files on your hard disk or disks.
