Solved Foxit PDF Reader: Settings file(s)?

I'd like to remove Foxit with Revo Pro and replace it with the portable from Portable Apps, but I've configured it extensively, and I can't find a file or foles or folder where those settings are stored, so that I can transfer them to a new installation. Any Foxit users here know what the location of the settings store is?

Found a way. Assuming the utility is on same name drive, in same name folder, with same name for app (all true for me), export the Foxit key from HKCU on the configured machine, and import that reg file to the reg of the unconfigg'd machine. Works.

The reason is that the portable version, whether direct download or PortableApps, records ALL settings to the registry, in the HKCU Software key. That's really annoying, but if you gotta live with it, you gotta live with it, for a fine PDF app.
