I need to add group within a group
e.g. COMPUTER\Users group to the “Backup Operators” group.
Wix provides a way to add a user to a group using the GroupRef Element but does not seem to provide an obvious way to add a group
Can this be done? If so how?
You’d need to write a CustomAction. It probably wouldn’t take too much to extend the existing User and Group CustomAction in the WiX toolset to support this. In fact, there is a feature request open for this behavior in the WiX toolset today. Maybe you could contribute the fix?
