I have no PinballX2 folder and when I look into the registry along that path there is no 53F4530D-802D-482A-86DD-F82D8EC5D615 for me to edit there.
Isn't Windows fun? I'm going to make a wild guess that you're running 64-bit Windows, is that right? If so, when you look with RegEdit, you need to look under this path:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
You could also just do a search (open RegEdit and press Ctrl+F) for 53F4530D - that'll turn it up.
What's going on is that Win64 sticks that extra Wow6432Node path element into certain keys that relate to 32-bit EXEs. Win64 does that on the sly, so that programs like Setup don't see them. That's why Setup reports the key without the \Wow6432Node\ element - Setup truly thinks it's looking at the key it lists in the log, but Windows is secretly changing the key behind Setup's back. You see the true key when you use RegEdit. I've spent many hours on wild goose chases thanks to this nefarious little trick.

I suspect you just have some old registry cruft from a past install. Is it possible that at some point in the past you might have renamed some folders, and didn't uninstall and reinstall all of your software when you did that?
Anyway, if you want to clear it up, your best bet is to probably go through a manual uninstall-reinstall cycle for PinballX to remove the old registry cruft.
- Run the "Add or remove programs" control panel
- Select PinballX
- Uninstall
- Download the PinballX installer
- Run it to do a fresh install
You might also be able to do a "Repair" operation from the "Add or remove programs" panel, if the PBX installer allows that.
Or you could just manually fix up the key so that it points to your current install folder. I'd go that route myself, but it might not be the only thing screwed up there so you might want to check the related entries to make sure everything looks right.
