I also removed any reference of Soaked from the this location:
HKEY_LOCAL_MACHINE
-Software
--Atari
and deleted the RCT3 Soaked folder located there. I don't know if this had any effect on the process or not, but I did it anyway.
If you have a problem with the Bad Version: 4 error message, check out this thread at the Atari forums. What's happened here is the you've uninstalled Soaked, but the game seems to think that something is missing. Just follow the instructions located there and above and you should be OK.
I just had the same issues and doing all of the above has allowed me to get the game back up and running again. Just thought I'd let you all know how to take care of this problem if you need to do so....
