HKLM
In windows it's HKEY_LOCAL_MACHINE is a db where your hardware/software data/configs/infos are stored/loaded.
In Ragnarok, after setting up using setup.exe, those settings are saved in HKLM(default location), thus it becomes a
global settings wherein whenever you load your RO client, those settings found on that db will be loaded.
HKCU, is also the same with HKLM where data/configs/infors are stored/loaded but the difference will be the settings/configs
will only become available when a certain user is logged on. If settings/configs are created by User A, then expect these
settings/configs will always be available for User A and not for User B.
There are actually 2 ways to fix this issue.
-First, when you are running Windows Vista/7 make sure to run your program
as an administrator. To do this right-click the executable file and select "Run as Administrator".
-Second, use the old setup.exe or patched setup.exe.. For newer clients, use the new setup.exe provided
when you downloaded/updated your kRO.
