You don't.

Ive downloaded alot of mods in the past 2 days and each mod we are playing is causing minidumps with regular sins and the expansion.. im going to try re-installing the game thru impulse again...

i have been tying out dolynicks sg mod, but it kept minidumping, and i was hoping it could tell me whats wrong.

You can use any Windows debugger that can read user mode memory dumps, though you'll not make any sense of its content, unless you know how to read assembler, operate on stack, read cpu regs and flags, etc. In order to make it more user friendly, you need source code and symbol database file for this exact version of executable.

If you still insist on checking the actual execution point where it crashes, use free Microsoft Debugging Tools for Windows (very solid set of tools for every software engineer).

Cheers

PS> Checking the actual address where it crashes may "rarely" lead to something, e.g. if it crashes in display driver, then you could try updating your drivers to eliminate possibility that driver is causing the crash.

Given how "insightful" the error messages are, I wouldn't expect too much...

I built a giant flesh grill in my basement. Whenever I need something draconian like Sins to play nice, I sacrifice crates of interns to a bright red flame for ten days. Eventually, the flames start speaking to me, and though I don't understand their words, I take heart in my successful ritual.

Well, my mod still crashes 9 times out of 10 when starting a game, but I assume that 1 time out of 10 is the will of the underworld at work.
