A conflict means two mods write the same file — for example two character packs that ship the same weapon replacement. The second install will collide.
How the client warns you
- Install failed: this file is already claimed by another enabled mod → disable the other mod in Mod Management and retry
- Conflict prompt (block) → only one of the two may be enabled
- Conflict prompt (info) → informational only (shared attachment files); both can stay on, the later write wins
Order of operations
- Read whether the prompt says claimed or conflict
- Claimed → disable the other mod → install again
- Block conflict → decide which one you want, disable the other
- Check both mods' state in Mod Management afterwards
Three rules of thumb
- Keep a single replacement mod per category (characters, vehicles, graphics)
- Add-on mods (dlc, AddonPeds, scripts) generally coexist; collisions come from shared assets
- Never force a conflicting install — one of the two will break in game
