In any event, this error is probably caused by a corrupted installation. A clean uninstall/reinstall should fix it.
If you are using EZCD 5 but not WinXP, follow the instructions at Easy CD Creator 5 Platinum will not install properly
If you are using it with WinXP, follow the instructions at How to cleanly uninstall / reinstall Easy CD Creator 5 in Windows XP
When reinstalling, don't reboot when the original installation is made. Keep going and install the latest update before rebooting. Hopefully, this should fix the problem.
