AWinstall can import a group of registry keys from the .reg file. Now you don't need to include external tools (such as RegEdit.exe) into setup package for merging .reg files just import such files into AWinstall project.

AWinstall currently supports the REGEDIT4 (from Windows 95/98/ME/NT) and REGEDIT5 (from Windows 2000/XP) .reg files. Older .reg file formats (from Windows 3.x) are not supported.

To import a .reg file into AWinstall project, right-click on task where you want to add registry keys and select "Add Keys from .reg file" menu item. The Open File dialog will appear. Select the .reg file to import and click Open.
