Well as it works for most other users, could you make an reproduceable 
test/example?

And what is KKLM?

Hello excuse me I made a mistake. I'am talking about HKLM (HKEY_LOCAL_MACHINE).

When I try to read/write a key/value in HKLM, Regor returns to me the value 
"null".

The openKey function returns always null when I try to open a subkey in HKLM.
So it works pretty well in HKEY_CURRENT_USER.

Found the "bug", but i would call it a problem ;-)
It is due security reasons.. So if your program would run as Adminstrator, it 
should work, but the workaround is to open the reg-key only in read mode!!

Example:
        System.out.println(System.getProperty("java.version") + "_" + System.getProperty("java.vm.version") + "_" + System.getProperty("java.vm.vendor"));
        Regor reg = new Regor();

        Key key = reg.openKey(Regor.HKEY_LOCAL_MACHINE, "SYSTEM\\CurrentControlSet\\Control\\Windows", Regor.KEY_READ);

        System.out.println("KEY ITSELF: >> " + key);
        System.out.println("VALUE: >> " + reg.readExpand(key, "SystemDirectory"));

        reg.closeKey(key);

You see, i use the openKey method with 3 parameters, where the 3rd parameter is 
the mode in which the reg-key-handle will be opened. So use: Regor.KEY_READ!
If you just use the method without 3rd parameter, it will use 
Regor.KEY_ALL_ACCESS which will not work and therefore you get "null" as 
returned key.

And if you want to modify the registry, you have to be in Admin-Mode (if I have 
time this summer, I will add these feature in the WinRegistry - so you can run 
it as admin - hopefully it will work in a library, because I use that method in 
some other java-GUI-programs).

Plase report back, if this is what you needed!

Ok, so weird.

I have supposed that the problem came from admin rights and I tested with the 
3rd parameter KEY_READ and it didn't work.

Maybe I was making something wrong because It works now.

Thank you for your reply.
