1. Do you need support for Assetto Corsa Competizione? Please use the proper forum below and ALWAYS zip and attach the WHOLE "Logs" folder in your c:\users\*youruser*\AppData\Local\AC2\Saved. The "AppData" folder is hidden by default, check "Hidden items" in your Windows view properties. If you report a crash, ALWAYS zip and attach the WHOLE "Crashes" folder in the same directory. Do not post "I have the same issue" in an existing thread with a game crash, always open your own thread. Do not PM developers and staff members for personal troubleshooting and support.
  2. As part of our continuous maintenance and improvements to Assetto Corsa Competizione we will be releasing small updates on a regular basis during the esports season which might not go through the usual announcement process detailing the changes until a later version update where these changes will be listed retrospectively.
  3. If ACC doesn't start with an error or the executable is missing, please add your entire Steam directory to the exceptions in your antivirus software, run a Steam integrity check or reinstall the game altogether. Make sure you add the User/Documents/Assetto Corsa Competizione folder to your antivirus/Defender exceptions and exclude it from any file sharing app (GDrive, OneDrive or Dropbox)! The Corsair iCue software is also known to conflict with Input Device initialization, if the game does not start up and you have such devices, please try disabling the iCue software and try again. [file:unknown] [line: 95] secure crt: invalid error is a sign of antivirus interference, while [Pak chunk signing mismatch on chunk] indicates a corrupted installation that requires game file verification.
  4. When reporting an issue with saved games, please always zip and attach your entire User/Documents/Assetto Corsa Competizione/Savegame folder, along with the logs and the crash folder (when reporting related to a crash).

The UIAutomationCore.dll error

  • Check that these files exist:

    C:\Windows\System32\UIAutomationCore.dll
    If not goto:
    "C:\Windows\winsxs\amd64_microsoft-windows-uiautomationcore_31bf3856ad364e35_6.1.7600.16385_none_0c0d85465bcceb37"

    From there... Copy/Paste the "UIAutomationCore.dll" to "System32" directory.

    Optional, only if ac doesn't start after copying the files.
    Then open a cmd and run as admin then type without quotes "cd C:\Windows\System32"
    Press enter.
    Then type exactly as below:
    regsvr32 UIAutomationCore.dll
    And do the same for the one below.

    C:\Windows\SysWOW64\UIAutomationCore.dll
    If not there goto:
    "C:\Windows\winsxs\wow64_microsoft-windows-uiautomationcore_31bf3856ad364e35_6.1.7600.16385_none_16622f98902dad32"

    From there... Copy/Paste the"UIAutomationCore.dll" to "SysWOW64" directory

    Again optional, only if ac doesn't start after copying the files.
    Open another cmd and run as admin then type without quotes "cd C:\Windows\SysWOW64"
    Press enter.
    Then type exactly as below:
    regsvr32 UIAutomationCore.dll

  • Some users have reported that they cannot start the sim if their main audio device is disabled. Obviously, enabling it solves this issue.
  • The windows firewall dialog might be requesting access for acs.exe - accepting the rule exception addition can solve this. If the dialog doesn't show up, you might have to go through the windows control panel options for the firewall and set it to allow acs.exe
As always for issues not mentioned here please search first for previous mentions and then start a different thread. You will likely be asked to include the log files from "My Documents\Assetto Corsa\logs" - the best way to do this is to right click on the logs folder and create a zip archive* which you can upload here.

* in Windows by default this is done by right clicking on the "folder->send to->compressed (zipped) folder"
