First of all, hi guys I made my own pc, using a ASUS P5N-D MoBo; Intel 775 3.2 Dualcore; 3 GB DDR2 Ram memory -3x 1 Gb (2x 800mhz, 1x 553mhz); ATI Radeon HD 5450 1GB DDR3; LC-Power LC6480S Scorpio-480W PSU FULLY Modular, I have Windows Ultimate x86 currently installed on my WD HDD 40 Gb ( I use that drive only for the system!) The problem is when I try to launch Need For Speed The Run... When I run it an error appears. It says that my current graphics card driver is 11.2; and I have to upgrade it to 11.7 before playing the game. Ok. I've downloaded AMD catalyst 11.7 but after installation it says that windows doesn't support tis operation... I've installed AMD catalyst 12.8 and the same problem comes up again... I've tried to do the next thing : What should I do in order to install the missing driver??
