This page may require cleanup to meet basic quality standards. The specific problem is: Needs information on DLC. Instructions on how to activate and download the extra DLCs should be added, in order to make things a bit easier to some users. You can help by modifying the article.

Game won't launch from Origin[edit]

  1. Go to <path-to-game>\Binaries\
  2. Rename MassEffect2.exe to MassEffect2Launcher.exe.
  3. Rename ME2Game.exe to MassEffect2.exe.
  4. The game should now launch from Origin.


If this doesn't work, make sure to rename the files back to their original states.

Physx Error on Startup[edit]

Install Nvidia Physx Legacy System Software[citation needed]
  1. Go to and Download the drivers.
  2. Install Nvidia Physx Legacy System Software.
  3. Run Mass Effect 2 again.

Cerberus Network autologin failure[edit]

  2. Navigate to Programs -> Turn Windows features on or off.
  3. In the tree stucture, check both boxes under Microsoft .NET Framework 3.5.1.
  4. Restart your system.

Black screen when entering/exiting planets[edit]

Black screen entering/exiting
If you get a black screen when entering/exiting a planet, specifically the shadow broker base, this is fixed by starting the game with the -nomoviestartup command. To do this:
  1. Go to the MassEffect2.exe file. It's in the .../Mass Effect2/Binaries folder.
  2. Create a shortcut to the MassEffect2.exe file. Right click the shortcut, and click 'Properties'.
  3. Add -nomoviestartup to the 'target' field. It should look like this: ...\Mass Effect 2\Binaries\MassEffect2.exe -nomoviestartup
This shortcut (skip the actual launcher) will not freeze when entering/exiting planets
Important Unfortunately, when using this command, your game WILL freeze when trying to enter the citadel. The only way to circumvent this is by saving the game, exiting and restarting it with the regular MassEffect2.exe

Dark lightning in cutscenes[edit]

Disable depth-of-field
  1. Open GamerSettings.ini
  2. Add under [SystemSettings]:

Clipping into walls/objects[edit]

This method involves Coalesced.ini file. Make sure you have understood what this means.
Add the option to noclip out of the object
  1. Under [SFXGame.SFXGameModeDefault] add:
Bindings=( Name="Add", Command="Ghost | OnRelease Walk")


Holding the NUMPAD + key in-game will now make you noclip until you release the button.

Game freeze on Illium[edit]

Walking through the ground level corridor, that connects to the other side of the map, under Liara's office may cause a black screen and CTD.
Enable windowed or windowed borderless mode
After passing through the corridor, it's safe to enable fullscreen mode again.

Unable to save any more games[edit]

Patch game files[8]
  1. Download Mass Effect 2 PCC Patcher
  2. Extract the program in <path-to-game>\Binaries\ and open it
  3. Provide the path for the following packages and load them
    Engine.pcc: <path-to-game>\BioGame\CookedPC\Engine.pcc
    SFXGame.pcc: <path-to-game>\BioGame\CookedPC\SFXGame.pcc
  4. Go to Gameplay tab and tick Increase max saves count
  5. Save packages

Long loading times with patch 1.02[edit]

Use Playwrite's MassAffinity program
  1. Download MassAffinity.
  2. If automatic Mass Effect 2 directory detection fails, manually select it.
  3. Click the "Run Game" button.


Use the included batch file if you need to set up again the tool

"Unable to authorize the listed DLC" error
  1. Download and extract ME3 Explorer.

Can invalidate your ME1 character's decisions in place of new ones
Remove the DLC
  1. Go to <path-to-game>\BioGame\DLC\
  2. Remove the DLC_DHME1 folder

Editing Coalesced.ini[edit]

Some of the fixes for this game require you to modify this special file, but editing it in the normal way will cause the game to crash.
Editing Coalesced.ini
  1. Locate your Coalesced.ini inside <path-to-game>\BioGame\Config\PC\Cooked
  2. Open it with a text editor that can handle UNIX-format files (Notepad++ is recommended)
  3. Make the changes you have to and save
  4. Download ME2IniFixer and extract it in the folder your Coalesced.ini file is
  5. Run it from there.


Do not use default windows notepad or Word. They will permanently corrupt your ini file.
  • Advanced users could also use Mass Effect 2 Coalesced Editor which is recommended
  • It might be necessary to make the Coalesced.ini file read-only (right-click -> Properties -> Attributes: Read-only) as the game can restore your edits. If you want to change anything in it, simply uncheck the Read-only box.

Increase shadow resolution[edit]

Increase shadow resolution
  1. Open GamerSettings.ini
  2. Add under [SystemSettings]:
  3. Save changes

Disable Post-Processing Effects[edit]

Some of the post-processing effects can be disabled in the game's GamerSettings.ini file. These effects include light bloom, and motion blur.
Disabling Depth of Field/Light Bloom/Motion Blur/Lens Flares
  1. Open GamerSettings.ini
  2. Under [SystemSettings] add one or more of the following lines:
  3. Save changes
A longer list of options that can be added and altered under [SystemSettings] can be found here.


Higher Resolution Character Textures[edit]

Install custom textures[11]
  1. Download your favourites dns's fixed TPF packs
  2. Download and extract ME3 Explorer.
  3. Open <me3explorer folder>\ME2Explorer.exe
  4. Enter Tools > Texplorer
  5. Select Start Multi-File Mode > Experimental > Generate Mod From TPF and give it your previously downloaded TPF
  6. Press File > Generate Mod
  7. Switch to Tools > Mod Maker and apply the .mod(s) by pressing File > Load Jobs and then Run > Run All/Run Some


The Jack_Final_524.tpf/.mod and LiaraLOTSB.tpf may corrupt in-game textures such as Jack's head and NPCs' eyes.
Doing the above on DLC content will make the game unable to authorize what you have installed. To fix this issue, refer to "Unable to authorize the listed DLC" error.
This mod may cause performance issues.
