“Runtime Error R6025 -Pure Virtual Function Call”

According to one of Microsoft’s Knowledge Base articles pertaining to this specific issue, Runtime Error R6025 is triggered when a Visual C++ based application indirectly summons a pure virtual member function in a context where a call to that specific function is not even valid. If you run into this error while developing an application, you simply added an invalid call to a pure virtual function somewhere in the application’s code. If that is the case, your compiler might even detect the invalid call and report the error to you while building the application, but in many instances this specific error can only be detected when actually running a compiled application. If you run into this error while using an off the shelf program or application, however, the root of the problem might be entirely different. In any case, the following are the most effective solutions that can be used to combat Runtime Error R6025:

Solution 1: Fix the application’s code

The simplest and most effective solution to this issue is simply sifting through the affected application’s code for the invalid call and removing it from the code. Obviously, however, this option is only viable if you’re running into Runtime Error R6025 on an application that you yourself developed. Here’s how you can rid your application’s code of the invalid call to a pure virtual function that’s making all this mess in the first place: Try running the application now, and it should run without spewing out Runtime Error R6025.

Solution 2: Run an SFC scan

You might be seeing Runtime Error R6025 because of corrupted system files. If that is the case, the recommended course of action is to run an SFC scan. The System File Checker utility is designed to check Windows computers for system files that have been damaged or corrupted and either repair any that it finds or replace them with cached, completely intact versions. To run an SFC scan, simply follow this guide.

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

Another possible cause of Runtime Error R6025 is missing Microsoft Visual C++ Redistributable packages. Windows computers depend on a wide array of different Microsoft Visual C++ Redistributable packages in order to successfully and seamlessly run Visual C++ applications, and missing Redistributable packages can lead to a Windows computer having trouble running Visual C++ applications. Here’s how you can check for and install missing Microsoft Visual C++ Redistributable packages on your computer:

Solution 4: Repair or Uninstall and then reinstall Microsoft Visual C++

You might be running into Runtime Error R6025 because the iteration of Microsoft Visual C++ that you have on your computer has somehow been corrupted and is no longer functioning as it should. If that is the case, you are either going to have to repair your installation of Microsoft Visual C++, or uninstall and then reinstall it from scratch in the event that the repair doesn’t work. To do so, you can use the Microsoft Visual C++ installer that came with the application that’s affected by this problem in the first place. Most, if not all, Visual C++ applications come with an installer for Microsoft Visual C++. If you would like to use this solution, you need to: In the event that Runtime Error R6025 still persists, repeat steps 1 and 2 from above, and then:
