After uninstalling the Toad 10.6 trial, I cannot uninstall Quest Install or install any other Toad for Oracle.
When trying to uninstall Quest Installer from add/remove programs or the uninstall.exe in the quest installer folder, the following message is given:
"GLFFEG~1.exe has encountered a problem and needs to close..."
When trying to install Toad 9.7.2 commercial version the following message is given:
"The update server is unavailable".
Trying to open the Quest Install from the Start | All Programs window gives an Access Violation.
