Hello there. I'm having a big problem. Ok what I did is delete all of my Jazz 2 stuff off the hardrive. (I didn't doing it by going into add and remove. I did it manually) Then today I wanted to reinstall it into my computer. I though since the files were gone the computer think that the computer would let me install it. So i put in the disk and it still thinks it's in the computer! It won't let me run the game, or uninstall it. So i can install it. So I go and explore the cd and try and start the install manually. It says that I already have a better version of Jazz 2 than 1.22 and it cancels. So i copy everything from the cd that makes the game work onto my computer. The game runs but I want to upgrade it to 1.23. So i download the patch but when I run it it says that Jazz 2 is already patched to 1.23. But it's not. Plus since I copyed everything over when I exit the game it freezes up my computer. Any help?

Well, you should've removed it through Add/Remove programs. JJ2 thought it was installed because its registry entries had not been removed, and I'm guessing the registry settings are causing your problem.

To get off to a clean start, you'll need to remove your JJ2 folder once again. Then, go to Start->Run, and type in regedit

Be careful and follow these instructions, and don't touch anything else in the registry.

Go to HKEY_LOCAL_MACHINE->Software->Epic Megagames. Remove all JJ2 entries.
Go to HKEY_CURRENT_USER->Software->Epic Megagames. Remove all JJ2 entries.

Now you should be able to install the game the proper way.

Thanks! That fixed the problem right up! Thanks for the help white rabbit.

I'm glad I helped. And also that your computer didn't explode.
