Where's the crash log?

[Timmeh]

Trying to set up mods but keep getting crashes.
Where can I find more info what's causing it?

Easiest way to sort out mod problems I found is using Wrye Bash and LOOT.

If you have OBSE it creates a log but never usually anything useful.
There is also this Crash Logger mod, useful for problems between pc and game.: https://www.nexusmods.com/oblivion/mods/48503?tab=description
A DLL that logs raw crash data -- the instruction pointer, x86 register values, and an attempt at identifying the source DLL (and instruction pointer relative to its module base).
