Not a major bug but affected me for a while :embarassed:. Whilst trying to install IceDragon (for the first time), installation was reporting that I was already running IceDragon and wouldn’t continue.
Your Operating System (and whether it’s 32bit/64bit); Windows 7 SP1 (x64)
This is not a bug.
Renaming installers to the same as the programs main process can result in this issue, because the installer thinks the program is installed and running once the installer is executed.
