In order to use RGB_Laboratory 1.1 in an effective way do the following:
Open "RGB Activator.exe" and it's supposed to show you a success message.
If it shows a fail message then the error is probably that you don't have the privilege to write into the registry, then ask your administrator to run the program, or if you're the administrator and it showes this message, right click on "RGB Activator.exe" and choose "Run as administrator".
Now you can use RGB_Laboratory 1.1 effectively, and open or save RGB Files.

Good luck.
