    1. CDUMM is running as administrator — drag-drop and mod install will often fail. Close CDUMM and relaunch WITHOUT 'Run as admin'.
    2. No snapshot present — Rescan Game Files before applying mods.

Which mod, and its Nexus page?

No response

What did you do, and what went wrong?

I updated the program, but it doesn't seem to be compatible with the 2.0 update.

Environment checks

• CDUMM is not running as administrator
• The game is not installed under Program Files
• The game exe does not have the "Run as administrator" compatibility flag set

Confirmations

• I'm on the latest CDUMM release
• I searched existing issues and didn't find a duplicate

Two things, both visible in your own attached report:

1. App Version: 3.15.1 — that version predates the 2.0 game update and cannot read its item table. Update to v3.16.0, which was released today for exactly this: https://github.com/faisalkindi/CrimsonDesert-UltimateModsManager/releases/tag/v3.16.0
2. Your report's own TL;DR flags it: CDUMM is running as administrator, which breaks drag-drop and installs, and there is no snapshot — run Rescan Game Files before applying.

So: update to 3.16.0, launch it normally (not as admin), Rescan Game Files, then apply. If something still fails on 3.16.0, attach a fresh bug report from that version.

[faisalkindi]

Update on this: go straight to v3.16.1, not 3.16.0. We found after the above that 3.16.0 had a separate 2.0 bug where mods applied fine but the game silently never loaded them (#383). 3.16.1 fixes that and repairs the game index on the next Apply by itself: https://github.com/faisalkindi/CrimsonDesert-UltimateModsManager/releases/tag/v3.16.1

[imedox]

CDUMM always replace current winmm.dll please make option on/off for it.

[faisalkindi]

@imedox That option already exists: Settings > Game > "Manage ASI loader (winmm.dll)". Turn it off and CDUMM will not touch winmm.dll at all -- it was added exactly for setups like OptiScaler that ship their own winmm proxy. ASI mod detection keeps working against whatever proxy DLL you bring (winmm/dsound/dinput8/version).
