If you’re greeted with the Windows Installer setup screen for an existing product everytime when you try to install a new program, you usually repair the existing application, or use the Windows Installer Cleanup Utility to remove the installer information of the existing application before reinstalling it. The problem is the Windows Installer Cleanup Utility Setup itself uses Windows Installer and hence it may not run in the above scenario. Here is an option which can be used to launch the Windows Installer Cleanup Utility without installing it.
2. Click Start, Run. type %temp% and press ENTER. This opens the Temporary folder of your user profile.
3. Double-click the file msicuu2.exe that you downloaded earlier in Step 1.
4. Running msicuu2.exe should automatically extract the setup package to the %temp% folder, under the folder named IXP000.TMP.
5. Copy the folder IXP000.TMP to your Desktop.
Note: Ignore (and dismiss) any Windows Installer prompts or errors that may be displayed at this time. You already got all the files you need, to run the Windows Installer Cleanup Utility manually.
6. Open the IXP000.TMP folder in your Desktop.
7. If you’re using a Windows 9x system (Windows 95/98/Me), rename the file MsiZapA.exe to MsiZap.exe. If you’re using Windows 2000/XP/2003, rename the file MsiZapU.exe to MsiZap.exe
8. Double-click the file msicuu.exe, and voilà, this starts the Windows Installer Cleanup Utility.
