How do I rap this type of key?

You could try Lapwing which would do it for you.
I don't usually work with RegRapper, so wait for Deuce to come along.

Reason being.....That key is the hard store of your current profile. Basically the "S-1-5-21-1715567821-1275210071-725345543-1003" is the profile ID on that pc and only that pc. It willnot be the same on any other pc you are on.

How it works is:

When you log in the hard store profile id key (What you have above) is copied to the HKEY_CURRENT_USER key. This is then the registry hive that is modified the whole time you are logged in. When you are logging out or shutting down the PC the HKEY_CURRENT)USER key is the copied back to the hard dtored profile id hive. Then the current user id is deleted. THe next time you log on it is then recreated using yur hard stored profile ID hive. ALSO, when someone else (Another user on the PC) logs in THEIR Hard stored profile ID is copied to the HKEY_CURRENT_USER and the same happens.

To Wrap this kind of location you just need to replace the HKEY_USERS\S-1-5-21-1715567821-1275210071-725345543-1003 with HKEY_CURRENT_USER. If you look into HKEY_CURRENT_USER\Software you will see the entry for softpointer.
Now using the system above when ever you go to another pc that profile ID for you will then be copied to the HKEY_CURRENT_USER hive on the machine, allowing it to work anywhere, because you will be using the HKEY_CURRENT_USER hive, which every windows pc uses to changews while logged in.

Hope I didn't get you too confused, basically just change it to HKEY_CURRENT_USER and it will work.
