Remove oracle from registry

Question

I've had to reinstall Oracle 9i Database without reformatting my hard drive.
Somewhere, I'm assuming in the registry, there is still a reference to my original oracle database SID. I've removed all instances of 'ora92' from my registry, but still have no luck when I try to reinstall the 9i database.
Is there a solution aside from reformating?
Thanks, ld

Hi,
Here is what I use:
1. Go to the regedt32
2. go to HKEY_LOCAL_MACHINE/SOFTWARE--Highlight the software you want to delete, then delete it.
3. go to HKEY_CLASS_ROOT -- expand the dropdown box go to the software you want to delete and delete that software.
Performing these 2 functions now alows you to delete all the folders from the appropriate drive.
4. go to the drive and delete all the appropriate folders.
Some software (most) provides services to the software itself and these could still be runnig and must be deleted.
5. re-enter regedt32 -- go to HKEY_LOCAL_MACHINE/SYSTEMS/CURRENT_CONTROL_SET/SERVICES
Highlight the service you want to remove and delete it. You will now notice that the item is no longer listed in the following directory: MY COMPUTER/CONTROL PANEL/SERVICES.
6. Now go to the startup menu and remove all the oracle files that need to be removed. This removes the startup icons. C:\documents and settings\all users\start menu
\programs\delete appropriate files.
You now have a clean machine to re install the software again.
Please make note of these directions for future reference.
Hope this helps.
