Mega Man Legacy Collection - General Troubleshooting Guide - Steam

  • Updated

While we really do hope everyone will be able to enjoy Mega Man Legacy Collection on PC, there are always cases where the game may not function correctly under certain software environments, hardware combinations, or otherwise.

If you are experiencing issues running the game, please try following the steps below to resolve your issue.

Troubleshooting Guide

  1. Check the game's system requirements
  2. Add the game's folder and files to your anti-virus program's exception/exclusion list
  3. Give Administrator Privileges to Steam and the game
  4. Update your Video/Graphics Drivers
  5. Update DirectX
  6. Verify the game’s cache in Steam
  7. Still having trouble?

1. Check the game’s system requirements

Please make sure you meet the minimum requirements for the game, outlined on the bottom of the game’s Steam Store page; if you do not meet the minimum requirements for the game, this may result in poor framerate, or the game not running properly.

Please note that some high end integrated graphics chips and modern laptop class discrete GPUs may work, but have not been tested, nor are they officially supported by Capcom.

If you’re experiencing performance issues while using a multi-GPU setup such as NVIDIA’s SLI or ATI’s Crossfire technologies, we recommend experimenting with disabling these settings, as they may cause compatibility issues with the game.

You can also run a third-party app such as System Requirements Lab for more information regarding compatibility with your hardware. Please note that System Requirements Lab is not officially supported nor endorsed by Capcom.

2. Add the game’s folder and files to your anti-virus program’s exception / exclusion list

Some issues with running the game properly may be attributed to certain anti-virus software preventing the game executable from launching due to a false-positive error. We recommend users add all of the following files and folders to the anti-virus and firewall exclusion list to prevent this issue:

Note: to quickly access the following folders, press Windows Key + R then copy and paste the folder URL below.

  • C:\Program Files (x86)\Steam\steamapps\common\MegaMan2

  • C:\Program Files (x86)\Steam\steamapps\common\MegaMan2\MMLC2.exe

For a guide on adding exceptions to your anti-virus software, please visit one of the following links:

3. Give Administrator Privileges to Steam and the game

If the game isn’t launching or running properly, ensure both Steam.exe and MMLC2.exe are running in administrator mode. This can be done by right-clicking on the .exe file and selecting “Run as administrator”.

Steam.exe location
C:\Program Files (x86)\Steam\Steam.exe

MMLC2.exe location
C:\Program Files (x86)\Steam\steamapps\common\MegaMan2\

4. Update your Video/Graphics Drivers

Try updating your video card drivers, as oftentimes outdated drivers can cause a variety of issues ranging anywhere from in-game graphical problems, to the game not starting, and more.

Additionally, please ensure that Windows Update has been run and that all the latest updates have been installed on your operating system.

5. Update DirectX

In addition to updating your video drivers, please ensure that has been properly updated for the game by running the DXSETUP.exe:

C:\Program Files (x86)\Steam\steamapps\common\MegaMan2\_CommonRedist\DirectX\Jun2010

We also recommend downloading and running the DirectX End-User Runtime Web Installer.

6. Verify the game’s cache in Steam

Finally, try verifying the game's cache in Steam. You can do so by following the steps outlined in this Steam support article (reposted below). This may find missing or damaged files that need to be repaired, even if you've just installed the game. You may also try temporarily disabling your anti-virus while verifying the cache or launching the game, as on occasion anti-virus programs may flag games or the files necessary to play them as a virus.

To verify the game’s cache, follow these steps:

  1. Restart your computer and launch Steam

  2. From the “Library” section, right-click on the game and select “Properties” from the menu.

  3. Select the “Local files” tab and click the “Verify integrity of game files...” button.

  4. Steam will verify the game's files - this process may take several minutes.

  5. Important: One or more files may fail to verify. This is normal for most Steam games. The files that fail to verify are local configuration files that should not be replaced as part of this process. You can safely ignore this message.

7. Still having trouble?

If you are still experiencing issues even after trying the steps above, please Submit a Request and provide all the information below in your ticket:

DxDiag report

  1. Open a "Run" dialog in Windows. This can either be done by typing "run" into Start Search, or by holding the Windows key and pressing "R." (Either method works in Windows Vista, 7, 8, 8.1, and 10.)
  2. Type "dxdiag" (with or without quotes) into the box that comes up.
  3. From the DirectX Diagnostic Tool window, wait for the tool to gather the information it needs, then click "Save All Information..." which will ask you to save a text file, named "DxDiag.txt" by default. Save this file somewhere where it will be easy to find, then attach it in your response.

Thank you for your support!
