I have just been working on upgrading FF 32-bit to 64-bit and thought I would document my findings. When doing a *silent* install of FF 64-bit on a machine with an existing 32-bit install, FF 64 is installed into *C:\Program Files\Mozilla Firefox *and the existing 32-bit install remains in *C:\Program Files (x86)\Mozilla Firefox*, and both installs are listed in *Programs and Features, *and can be launched separately. FF 64 will create a new profile. When running the GUI 64-bit installer, the installer detects the existing 32-bit install, and will perform an *in-place* upgrade, converting the 32-bit installation to 64-bit. This is evidenced by the confirmation button in the GUI being named *Upgrade, * rather than *Install, *and when choosing to customize the install, the install directory is pre-filled as *C:\Program Files (x86)\Mozilla Firefox.* To perform an *in-place* upgrade *silently*, one can set the install directory path on the command line (from Firefox v62 onwards) e.g. */InstallDirectoryPath="C:\Program Files (x86)\Mozilla Firefox"* As far as I can tell, this performs a successful *in-place* upgrade from 32-bit to 64-bit FF retaining use of the same profile. (Although, yes, there is the downside of having 64-bit binaries living in *Program Files (x86).)* HTH, Dafydd On Wed, 9 Sep 2020 at 16:23, Harkins, Steve via Enterprise < [email protected]> wrote: > Mike, > > > > If we’re changing from 32-bit to 64-bit, Firefox won’t be in the same > directory (C:\Program Files, instead of C:\Program Files (x86).
