Some InfoMaker features require the use of the IM.INI file, but many features use the registry to get and store configuration information. Normally, you should not need to access or modify items in the registry.
Information related to your preferences (such as the way you have arranged your views in the painters and the shortcut keys you have defined for InfoMaker menu items) is stored in HKEY_CURRENT_USER/Software/Sybase/InfoMaker/12.5.
Installation-related information is stored in HKEY_LOCAL_MACHINE/Software/Sybase/InfoMaker/12.5.
