How to completely & cleanly uninstall the Oracle ODBC client package
Always take great care when editing the Registry. Always back up your Registry first in case of problems (the following instructions include a step for doing that).
- Reboot the PC and then login with an account that has full administrative rights on the local PC. Avoid opening any unnecessary applications (email/etc.).
- Delete any Oracle folders in the PC's C:\ drive (i.e. C:\Oracle, C:\Oracle10g, C:\Oracle9i)
- Open Windows Registry by typing regedit in the Start menu's Search box
- When the Registry Editor opens, back it up by clicking File > Export... and save the file to a safe location just in case you need to restore your Registry after doing the following.
- Locate the following registry entries via regedit (note that some of these may not exist, but check them all):
- in HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\, delete VGER folder
- in HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\ODBC Data Sources, delete VGER REG_SZ entry1
- in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Oracle\, delete KEY_OraClient10g_home folder
- in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBC.INI, delete everything EXCEPT ODBC Data Sources
- in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBC.INI\ODBC Data Sources, delete all entries except (Default)
- in HKEY_CURRENT_USER\Software\ODBC\ODBC.INI\ODBC Data Sources, delete VGER REG_SZ entry
- in HKEY_CURRENT_USER\Software\ODBC\ODBC.INI\, delete VGER folder
- Reboot the PC
1 Note that some customers report this entry cannot be deleted. If you find this to be the situation, leave it as it is and continue with the uninstall steps.
