Recovering from an unsuccessful uninstall

If an uninstall is unsuccessful, files, registry entries, and services may remain that should have been deleted. This topic provides guidelines for both Easy and Custom installations.

Procedure

For an Easy, first install:
1. Remove Informix by executing the Informix uninstall command:
```
install_location\informix\bin\ifxdeploy.exe -u install_location\informix -delifx
```
1. Remove the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Informix\Online\ol_cognoscm
2. Remove the installation folder install_location
3. If this is the only InstallAnywhere-based install on your machine, you can remove the InstallAnywhere registry file: %PROGRAM FILES%\Zero G Registry\.com.zerog.registry.xml
For all other installations:
1. Remove the installation folder install_location
2. If this is the only InstallAnywhere-based install on your machine, you can remove the InstallAnywhere registry file :
  On Windows (hidden directory): %PROGRAM FILES%\Zero G Registry\.com.zerog.registry.xml
  On UNIX: registry file: .com.zerog.registry.xml located:
  - If logged in as root, the global registry is located in /var
  - If logged in as a user, it is located in the user’s home directory.
  If you are not sure about the status of InstallAnywhere installations, you can simply rename this file in order to keep a copy of it.
