I can't uninstall the program construction zone for windows 95-98 with the MS add or remove programs from my Windows XP. I added it for my grandkids and now can't delete it to free up space. This is the message I get.The log file 'C:\Program Files\Mattel Media\Matchbox\Caterpillar Construction Zone\Construction Zone\Data\Uninstallcat.isu' is not valid or the data has been corrupted Uninstallation will not continue. 1 person got this answerI do too

I tried installing and uninstalling, didn't work but I tried using Revo-Uninstaller as Soumya_Segupta suggested and it worked. Thanks all!
