Unexpected Error; quitting - when installing IP Tracker Free

This is on XP Pro SP3 and I have full admin rights. I have many apps installed on this laptop all running well. Any idea what might cause this. I get the error both when attempting to install, repair and uninstall. AV turned off. Also get it when attempting the run the app after an install. Other apps are installing just fine.

Any ideas would be appreciated.
