What is “CONCRT140.dll is missing” error

CONCRT140.dll is missing is quite a popular error related to Microsoft Visual Studio software. The issue restricts users from opening certain applications and videogames with an error message. Here is the list of all types of messages one can receive when facing this error:

“The code execution cannot proceed because CONCRT140.dll was not found”
“concrt140.dll is missing”
“concrt140.dll could not be located”
“This application failed to start because concrt140.dll was not found”
“Error loading concrt140.dll. The specified module could not be found”
“There was a problem starting concrt140.dll. The specified module could not be found”
“C:\Windows\System32\CONCRT140.dll is either not designed to run on Windows or it contains an error”

CONCRT140.dll is a DLL (Dynamic Link Library) installed by Visual C++ Redistributable Packages. These components are very important and widely applicable with many Windows apps. Should one of them be missing or damaged, no application based on Visual Studio will open. Luckily, it is often quite easy to fix such errors fast and long-term at the same time. We have prepared a separate guide to help you recover the file and open the software you need. Scroll down below to see all of the fixes.

There are special repair utilities for Windows, that can solve problems related to registry corruption, file system malfunction, Windows drivers instability. We recommend you to use Advanced System Repair Pro to fix the “CONCRT140.dll is missing” error in Windows 11, Windows 10, Windows 8, or Windows 7.

1. Reinstall Visual C++ Redistributables

As discussed above, DLL errors are often related to problems with Microsoft Visual Studio. Thus, it is very possible that the error appears due to corrupted or missing Redistributable packages. We first recommend you to try and repair Microsoft Visual C++ Redistributable using the steps below. If this does not resolve the problem, you can reinstall the software as well.

  1. Open this Visual Studio page.
  2. Click on the download links for vc_redist.x86.exe and vc_redist.x64.exe.
  3. Execute both of these files and start the process by clicking Install. If you have Visual Studio already installed, the setup will offer to either Repair or Uninstall it. Choose Repair and close the window once finished.
  4. In case it turns out some Visual C++ Redistributables are not installed, the setup will offer to do it.
  5. Follow on-screen instructions and finish the installation.

2. Check integrity of the system files

Scanning your system for missing and corrupted files with in-built Windows utilities may help sort out the error. Try to do it using both SFC (System File Checker) and DISM (Deployment Image Servicing and Management) scanning utilities, which will detect and restore absent components, if any. Make sure to use both utilities as they may have a different impact on solving the problem. This is how:

Using SFC

  1. Open Command Prompt by typing cmd into the searching loop next to the Start Menu button.
  2. Right-click on Command Prompt and choose Run as administrator.
  3. Once the console is opened, type the sfc /scannow command and click Enter.
  4. When the fixing process is done, restart your computer.

Using DISM

  1. Open Command Prompt as we did in the previous step.
  2. Copy and paste this command DISM.exe /Online /Cleanup-image /Restorehealth.
  3. Click Enter and wait until Windows ends the scanning and fixing.
  4. Once done, restart your PC and try to open the problematic program again.

After performing both of these scans, attempt to boot the application you struggled with. If this does not work, get down to the other solutions mentioned below.

3. Re-register DLL files manually

Windows allows its users to reinstall many components themselves using Command Prompt. This is exactly what we are going to do in this step. Instead of re-registering the CONCRT140.dll file separately, let’s do it with all so to make sure nothing is missing. Follow these instructions:

  1. Open Command Prompt like we did in the previous step.
  2. Copy-paste this command for %1 in (*.dll) do regsvr32 /s %1 and press Enter.
  3. The process may take a couple of seconds. Once done, restart your PC and check whether you can finally open the problematic application.

4. Reinstall the problematic application

In case performing the previous steps did not eradicate the issue completely, also try to reinstall the application you are unable to open. Maybe you restored the file successfully, but it is the application itself that cannot identify it. Try to install again so it does.

  1. Left-click on the magnifying glass right next to Start menu and search for Control Panel.
  2. Open it up and choose Uninstall a program under Programs.
  3. Select the program dealing with the error and click Uninstall.
  4. Finally, install it again and check if the error is fixed.

5. Scan your system for malware

Sometimes people may be unaware of accident malware or unwanted programs that could sneak into the system. Malware is notoriously known to cause various clutter inside of a system. This is why it is worth giving your PC a full-blown scan. You can use either in-built Windows Defender or install advanced anti-malware software that will combat threats that Windows could miss. We recommend you to use an antivirus developed by Malwarebytes – a trusted and talented group of experts constantly maintaining their software to combat both minor and global threats. It is now available for Windows 11 as well. You can download it now using the link below and try a 14-day trial of the ultimate antimalware experience for free.

6. Use System Restore Point

In case nothing works out and trying to find the right solution results in constant failure, System Restore may help you get out of this crisis. Unless you installed Windows just now, there should be a backup point stored by the system when DLL problems were out of their current existence. Therefore, let’s get your system back to its latest backup.

  1. Open Control Panel as we did in the steps above.
  2. Set View by to Large icons and choose Recovery. You can also find it using the search box.
  3. Click Open System Restore and select Next.
  4. Choose a restore point you want to you from the list and click Scan for affected programs to see what programs will be deleted upon restoration. If there are no Restore points visible, try to choose Show more restore points.
  5. Click Next again and Finish to finalize the process and let Windows restore your system from the selected backup.

We hope this finally helped you launch the application you had issues with.


DLL errors are quite easy to fix simply because you know what’s missing. The error message draws enough details to figure things out and solve the problem eventually. We hope it was exactly your case and there is no such error making its presence known on Windows 11. If you experience any other issues like malware or errors, do not hesitate to look for them on our website.
