while trying to install EG the a message indicating that( EG is already installed and if you want to reinstall remove EG first from control panel - add remove programs) stop the installation process .
the software was installed before but have been removed manually from the program files folder .so, I’ve tried to uninstall it first from (add remove programs ) but it did not work. there seems to be some values in the registry need to be removed.
how to fix this problem? Is there cretin values in the registry I should delete what are they or should I delete each EG related value in the registry
