Uninstalling Oracle

I unwittingly downloaded and installed two instances of Oracle 11g r2 Enterprise Edition on my laptop. I also have 11g Express edition installed, as well as sqldeveloper and datamodeler. I want to uninstall all of it. But either I can't find them in programs under control panel or, if i can find them (via start - programs), then there is no option to uninstall. How do I uninstall them?

Go to  your Programs Find Oracle Home then find the Universal Installer you will uninstall from here.

The Oralce installer still leaves pieces laying round.

If you want to remove ALL Oracle products, I prefer a manual delete.  If you want to leave some Oracle and remove others, the installer is the best.

If you want informaiton on a manual install just ask or Google around.  The steps are out there.

I tried solutions 1 and 3. I deleted the database in home_1. However, when I use the Universal Installer to deinstall, I get a dialog box that tells me to go to a deinstall executable file on my c drive. In the respective folder are three deinstall files with extensions .bat, .pl, and .xml. When I click the batch file, it goes to the command prompt which says: "Checking for required files and Bootstrapping..." Then, a few seconds later a screen pops up that says some files were copied. But then screen goes out almost immediately. I wait a few minutes and nothing happens.

You need to go to command prompt from there you can drag the bat file to the command window you can see the progress there

dariusg, that's a neat little trick but still having problems. See attached file.

Do you have some Oracle products and a database you want to preserve?
Darius GhassemCommented:
You can just delete the folders as well

>>You can just delete the folders as well

This is the manual uninstall I mentioned earlier.  This by itself isn't good enough becuase of the Inventory file.  Oracle will still think it is installed.

I do not have any Oracle products or Oracle databases I want to keep.
