I am getting an error when i run MentalRay software

Greetings to you all,
I recently bought a Mental Ray software to help me produce unrivaled images through designs created using the computer and data that enables the creation of digital content.
I use Windows XP with a memory capacity of 8GB.
Whenever I try to run Mental Ray software, I get this error?
Is it still a problem with the memory?
Kindly help out.
