I installed Installer3.0 and something has gone wrong. Whenever I try to install anything it states that the installer is not properly registered. And if I try to uninstall anything I get the same message.
If I download and try reintalling version 3.0 it says that it is already installed.
What can I do to revert to the previous version of the installer
