Hm... I can do it, but the average Joe can't. And also, I take daily differential registry backups and I know how to resolve most windows boot-killing errors:P
Comdlg32.ocx is not distributed with Vista.
To fix the comdlg32.ocx error:
1: Download the zip (it's the file from my computer, WinXP SP3)
2: Copy it to the FLAM install folder
3: Use an admin account and type in command prompt (or "Run") regsvr32 C:\[path to FLAM folder]\comdlg32.ocx
