Reg2Nsis – convert registry info into NSIS commands. Converts registry information (from registry itself or REG-file) into NSIS-script commands.
Automatically substitutes $WINDIR, $SYSDIR, $PROGRAMFILES and $COMMONFILES constants instead of corresponding special folder names (based on current Windows settings). Include generated script into your installer with the !include.
