OK, first remove all BG2 files that still exist on your harddisk (the only thing you can keep are old savegames you want to keep - put them in a folder somewhere). Then, start a new, clean install. When it asks for CD2, put it in your CD-ROM drive, but do NOT click 'OK'. Instead, wait for about 1-2 minutes until it's completely spun out. THEN, click OK. IF it worked, it will not go on to ask for CDs 3,4 and 5 immediately, but procceed the installation from CD2. Repeat the same pattern for CDs 3 and 4: when the PC prompts you to put the next CD in, WAIT some time before you click OK.

This worked for me when I had the same problem - hope it helps in your case as well! Good luck [img]smile.gif[/img]
