RightFax Universal Uninstaller

From psadt | Evergreen Application Management
Jump to navigation Jump to search



RightFax securely sends and receives documents from a variety of sources via the cloud or telephone connections.

It has to be one of the worst applications I’ve worked with as an automator. Every version that is released has a new type of installer that works differently to previous versions. It throws random errors, but not consistently. It fails to quit, but not consistently. It must be uninstalled using the executable – but, you guessed it, not consistently (the latest version can ONLY be uninstalled with the MSI, which complains if not called from the Setup.exe, and Setup.exe has no uninstall option when run manually 🙂 )

Bring on the challenge!
