Catastrophic Failure is caused by missing system files or broken system registry structures. This is a critical sign of an unstable system that is typically caused by improper maintenance of the computer.

Please first make sure you login with Administrator privileges on your PC when installing/Uninstalling VisiLogic.

Go to: Control Panel > Appearance and Personalization > Folder Options > View Tab > Hidden files and folders > Mark the "Show hidden files , folders , and drives"

Then go to: C:\Program Files (x86)\InstallShield Installation Information

You should see few folders with "Product GUID" folder.

Usually the GUID is {8A9D3251-0E92-4C91-80AE-05EEAFC6467D}. Make sure it's related to VisiLogic by opening the "Setup".ini" and see Appname=VisiLogic

If it does, please delete the entire folder.

Reboot your PC and try to install/uninstall VisiLogic from your desktop.
