I called Microsoft on this and they were no help.I keep on getting a 1335 Error on installinG FSX on a new Dell quad core computer with dual 8800 Ultras. I only have 1 drive a Blue Ray dvd/cd combo. I read a post to lower the memory to 256K in the boot.ini that seemed to get me mid way to disk 2. I am now on my 10th attempt. Any help?

I found these possible solutions on the Internet: http://consumer.installshield.com/kb.asp?id=q110742http://support.microsoft.com/kb/314810Best regards,Jim

I resolved this error by re-installing it 10 times. Each time the install went further and further - until the 10th time it took. Not the solution I was looking for, but I am flying now.
