Fix: Microsoft Visual C ++ Runtime Library Error – Runtime Error R6025

Runtime Error R6025 is an error related to Microsoft’s Visual C ++ development environment.Any application or program that was 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 that were developed with Visual C ++ (Steam games for example), and applications 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 a the context in which a call to the function is not valid. If you get this error while developing an application, you just 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 actually running a compiled application. However, if you encounter this error while using a pricing program or application, the root of the problem 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 simply to sift the affected application’s code for the invalid call and remove it from the code. Obviously, however, this option is only 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 that is being 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 triggered and the code stops running, simply parse the call to see exactly where in the application’s code the function is called, and then delete the call.

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 either repair any files it finds or replace them with fully intact archived versions. To run an SFC scan, simply follow the instructions below.

Enter theelevatedCommand Prompt by right clicking on the start menu icon. Select Command Prompt (Admin) from the list. You can also navigate to the command prompt using the Win + Xkeyboard shortcutsand 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 a bunch of different Microsoft Visual C ++ Redistributable packages to run a Visual C ++ application successfully and seamlessly, 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 a number of different Microsoft Visual C ++ Redistributable packages.What you need to do is find out if there are any packages that are missing and 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 theDownload 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 installation of Microsoft Visual C ++, or uninstall and then reinstall it from scratch in case 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 the partition of your hard drive the Steam directory is located in, and represents any parent folders (if any) the Steam directory has.
  2. Locatevcredist_x86.exeand double click on it to run it.
  3. When asked if you want to Repair the installation or Repair it, choose Repair.
  4. Go through the installer, wait for the repair to be done and check if the problem got resolved.

In case Runtime Error R6025 still exists, repeatsteps 1 and 2from 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.
