I have seperately tried to install Office XP and Office 2000 Premium on my PC running XP Porfessional. On each installation, it stops at the same point with the message "Error 1311. Source file not found: Q:\OFFICE1.CAB. Verify that the file exists and that you can access it." The file is certainly there, on both setup CDs, but it doesn't seem to want to access it. Any ideas anyone?
