Assuming a Windows installation, do please refer to this: • Uninstall all Oracle components using the Oracle Universal Installer (OUI). • Run regedit.exe and delete the HKEY_LOCAL_MACHINE SOFTWARE ORACLE key. This contains registry entires for all Oracle products. Clock Flash Screensaver 1.1 on this page. • Delete any references to Oracle services left behind in the following part of the registry: HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services Ora* It should be pretty obvious which ones relate to Oracle.

• Reboot your machine. • Delete the 'C: Oracle' directory, or whatever directory is your ORACLE_BASE. • Delete the 'C: Program Files Oracle' directory. • Empty the contents of your 'C: temp' directory. • Empty your recycle bin.

In this post i try to explain how we can remove Oracle. I am trying to dinstall Oracle 11g client on Windows 7. H Force Keygen For Idm. How to Manually Remove Oracle Server.

Calling additional attention to some great comments that were left here: • Be careful when following anything listed here (above or below), as doing so may remove or damage any other Oracle-installed products. • For 64-bit Windows (x64), you need also to delete the HKEY_LOCAL_MACHINE SOFTWARE Wow6432Node ORACLE key from the registry. • Clean-up by removing any related shortcuts that were installed to the Start Menu. • Clean-up environment variables: • Consider removing%ORACLE_HOME%. • Remove any paths no longer needed from%PATH%. This set of instructions happens to match an almost identical process that I had reverse-engineered myself over the years after a few messed-up Oracle installs, and has almost always met the need.

Note that even if the OUI is no longer available or doesn't work, simply following the remaining steps should still be sufficient.

Further edits are appreciated (and then please remove this comment), if a way can be found to maintain these considerations.).

First of all you should use the deinstall tool as recommended by Oracle. Then if this fails have a look at this document:, it provides detailed instruction how to remove everthing. This documentation is for Oracle Client 11.1, however the principle should be the same for 12c. Actually the documentation for 10.2 is even more complete: Perhaps some files are locked and you can not delete them by default, for example file oci.dll. Solution is to rename the file, e.g. Oci.dll_x and then reboot your PC. After reboot you can delete the file.
