RegDBGetDefaultRoot

InstallShield 2024 » InstallScript Language Reference

Project: For InstallScript MSI and Basic MSI projects, it is recommended that you use the Registry view in InstallShield instead of creating registry keys and values through InstallScript code. Handling all of your registry changes in this way allows for a clean uninstallation through the Windows Installer service.

The RegDBGetDefaultRoot function returns the root key that is used by the general registry-related functions.

Note:This function supports the 64-bit parts of the registry by using the REGDB_OPTION_WOW64_64KEY option. For more information, see REGDB_OPTIONS.

Syntax

Note:The return value HKEY_USER_SELECTABLE indicates that a subsequent registry function call uses HKEY_LOCAL_MACHINE as the root key if the ALLUSERS system variable is non-zero when the function is called, or uses HKEY_CURRENT_USER as the root key if ALLUSERS is FALSE when the function is called.
