I Have just bought a new computer and was in the process of installing my printer drivers/software etc when an error message popped up saying "Fatal Error During Instalation" (Print Screen of error is attached) I have tried all of the solutions noted on the HP website here http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00461235&lc=en&dlc=en&cc=uk#N95 with no success! (I have downloaded the correct/updated drivers from the HP website) My Printer is an "HP Photosmart C4380" and the operating system i am running is "Windows 7 Ultimate 64bit" My previous computer was running the "Windows 7 Professional 64bit" and worked perfectly. If i just plug in the printer the drivers are automatically installed by windows so i can use the printer except for things like scanning. I believe that the drivers installation is causing the problem so if anyone can find out how to only install the HP Printing Software and not the drivers i think this might work. Thanks for your help!
