Runtime Error R6025 is an error related to Microsoft’s Visual C ++ development environment. Any application or program developed using the Visual C ++ studio was among the possible targets for this error. Runtime Error R6025 has been seen to affect both applications and programs developed with Visual C ++ (Steam games, for example), and application users are affected by this error developed by Visual C ++. The entire error message that is seen when you run into this error reads:

Runtime Error R6025
-Pure Virtual Function Call

According to one of Microsoft’s knowledge base articles regarding this particular issue, Runtime Error R6025 is triggered when a Visual C ++-based application indirectly invokes a pure virtual member function in the context in which a call to the function is not valid. If you get this error while developing an application, you need to add an invalid call to a pure virtual function somewhere in the application’s code. If so, your compiler might even detect the invalid call and report the error to you while building the app, but in many cases, this particular error can only be detected. When running a compiled application. However, if you encounter this error while using a pricing program or application, the problem’s root may be completely different.

In any case, the following are the most effective solutions that can be used to combat Runtime Error R6025:

Method 1: Edit the application’s code

The simplest and most effective solution to this problem is to sift the affected application’s code for the invalid call and remove it from the code. However, this option is viable if you are running into Runtime Error R6025 on an application that you developed yourself. Here’s how you can get rid of your app’s invalid call’s code to a pure virtual function that is creating all this mess in the first place:

  1. In the affected application’s code, replace the pure virtual function called on execution designed to call the Windows API function DebugBreak.
  2. When DebugBreak is joined, using the debugger triggers a hard-coded breakpoint, at which point the code stops running.
  3. Once the breakpoint is activated, and the code stops running, parse the call to see precisely where the application’s code the function is called and then delete it.

Try running the application now, and it will run without spitting out Runtime Error R6025.

Method 2: Run an SFC scan

You can see Runtime Error R6025 due to a corrupt system file. If this is the case, the recommended action is to run an SFC scan. The System File Checker utility is designed to check Windows computers for corrupted or corrupted system files and repair any files it finds or replace them with fully intact archived versions. To run an SFC scan, follow the instructions below.

Enter the elevated Command Prompt by right-clicking on the start menu icon. Select Command Prompt (Admin) from the list. You can also navigate the command prompt using the Win + X keyboard shortcuts and then select it.

After running the command prompt, type the following command mentioned below to run the SFC scan. Make sure you don’t cancel the process and wait for it to complete. The results will be displayed once the scan is complete.

sfc / scannow

PressEnteron the keyboard after typing. It will start scanning for corrupt or missing files on your PC.

Method 3: Install any missing Microsoft Visual C ++ Redistributable packages

Another possible cause of Runtime Error R6025 is the lack of the Microsoft Visual C ++ Redistributable package. Windows computers depend on many different Microsoft Visual C ++ Redistributable packages to successfully and seamlessly run a Visual C ++ application. And missing Redistributable packages can lead to a problematic Windows PC when running Visual C ++ applications. Here’s how you can check for and install missing Microsoft Visual C ++ Redistributable packages on your computer:

  1. Open the Start Menu.
  2. Search for “ add or remove programs”.
  3. Click on the search result titled Add or remove programs.


  4. Wait for the list of programs installed on your computer to be filled out.
  5. In the list of programs installed on your computer, you will see several different Microsoft Visual C ++ Redistributable packages. You need to find out if any packages are missing and are currently not installed on your computer.

  6. You can download the installer for any missing Redistributable packages from your computer from the following links, or if you need another Redistributable package, from the download section on the official website of
    Microsoft : Microsoft Visual C ++ 2010 Redistributable Package (x86)
    Microsoft Visual C ++ 2012 Redistributable Update 4
    Microsoft Visual C ++ 2013 Redistributable Package
    Microsoft Visual C ++ 2015 Redistributable Package

Method 4: Repair or uninstall and then reinstall Microsoft Visual C ++

You may be running into Runtime Error R6025 because the repetition of Microsoft Visual C ++ that you have on your computer has somehow corrupted and is no longer functioning as it should. If that is the case, you will either have to repair your Microsoft Visual C ++ installation or uninstall and then reinstall it from scratch if the repair doesn’t work. To do so, you can use the Microsoft Visual C ++ installer that came with the application affected by this issue in the first place. Most, if not all, Visual C ++ applications come with an installer for Microsoft Visual C ++. If you want to use this solution, you need to:

  1. Navigate to the directory on your computer where the installer for Microsoft Visual C ++ is stored. For example, if you are running into Runtime Error R6025 while playing Skyrim through Steam, the installer will be located in the following folder as vcredist_x86.exe :
    X: Steam SteamApps Common Skyrim VCRedist
    Note: In the above directory, X represents the mail corresponding to your hard drive’s partition drive the Steam directory is located in and means any parent folders (if any) the Steam directory has.
  2. When asked if you want to Repair the installation or Repair it, choose Repair.
  3. Go through the installer, wait for the repair to be done, and check if the problem got resolved.

In case of Runtime Error R6025 still exists, repeat steps 1 and 2 from above, then:

  1. When asked if you want to Repair installation or Remove installation, select Remove.
  2. Go through the installer and wait for your Microsoft Visual C ++ installation to be removed.
  3. Once Visual C ++ has been uninstalled, runvcredist_x86.exeagain.
  4. This time around, the installer will know that Microsoft Visual C ++ is not even installed on your computer, so going through it will reinstall Visual C ++.
  5. Once Visual C ++ has been reinstalled, check to see if the problem is fixed.
