"Error 1609" fix problem:
To complete the installation a Users group must be created. This can be done from Control Panel>Administrative Tools>Computer Management and then expanding System Tools>Local Users and Groups>Groups. Right click Groups and choose New Group, name it "Users". Or execute the attached batch file which contains the command "net localgroup Users /add" which will add the Users group. It will report if the group already exists or it will create the group.
