After having done what looked like a proper UN-install of Flash Builder 4.5, I am trying to install the FB 4.6 upgrade. I get:
A conflicting or prerelease version of Adobe Flash Builder exists on this computer. The conflicting version must be removed before installing from the current media.
I dont know what this is, so spending an hour on the phone finally got me to Ankush Bangroo <firstname.lastname@example.org> who knew how to fix this.
download the cleaner tool from the following site and run it, remove the "Adobe Flash Builder" item, then reboot.
Now, you can do a proper install of Flash Builder 4.6.
