I am trying to install the latest update but I just get an option to remove or repair the installation. If I select repair, it goes through its repairs. When I launch Toad I get the prompt to upgrade. Stuck in a loop trying to upgrade.
Not a great deal of detail to go on... but one remedy to your issue would be to just uninstall the beta, go straight to the beta download page, download and install... a Toad Beta reboot will get you going again.
