How To Fix Runtime Error R6025

The Runtime error R6025 is an error that occurs with the Visual C++ framework. The error is shown when your application calls a “pure virtual function” in a context that is not valid for the function. If you are not a developer, this generally means that the application’s code is incorrect; and if you are a developer, it means that you need to redesign some of the functions inside your program. These steps are going to show you what to do to fix the problem:

What Causes Runtime Error r6025?

The Runtime r6025 error normally appears in this format:

“Runtime Error R6025
– Pure Virtual Function Call”

This error is caused with a problem in the coding of a certain application. C++ is the coding language that applications are developed in, and it’s often the case that the developer who created the application either didn’t code it correctly, or missed some part out. If you’re a user of the software, it’s recommended that you either contact the developer about the issue or download the latest version… and if you’re a developer, you should look at the various “pure virtual functions” that you have in your system, and fixing them.

How To Fix Runtime Error r6025

Step 1 – If Coding In Visual C++, Change The Code

Calling a pure virtual function is a programming error, so if you’re developing a program & are seeing this error, you need to find the “pure virtual function” and rewrite the code so it is not called. To fix this problem follow these steps:

Replace the pure virtual function with an implementation that calls the Windows API function ‘DebugBreak’.

When using the debugger, DebugBreak will cause a hard-coded breakpoint.

When the code stops running at this breakpoint, you can view the callstack to see where the function was called.

Another way to find a call to a pure virtual function is to set a breakpoint on the _purecall function that is found in PureVirt.c.

Breaking on this function has the advantage of keeping the stack intact so that you can trace what is occurring.

Step 2 – Uninstall / Update The Program Causing The Error

If you’re a user seeing this error, you can stop it from appearing is to uninstall or update the program that is causing the error. It’s often the case that downloading a program like this to use on your PC will result in your computer saving parts of it incorrectly, leading to the error.  Uninstalling the program will remove it from your system, stopping the error. You should then try to download an update for the software before installing again. To uninstall the application, please use the tutorial below:

Click Start, then select Control Panel.

Select Programs.

Once you have done that click Uninstall a program.

Then you will see a list of programs, choose the specific program and select Uninstall.

Then follow the on-screen instructions.

To update the program, you can download the necessary patch from the programs website and then install it. This is very easy to do.

Step 3 – Clean Out The Registry

• Download this registry cleaner

The ‘registry’ is one of the biggest causes of problems for the Windows system, and is often the reason why runtime errors such as the r6025 error show on your PC. The problem is that the registry is one of the most important parts of Windows – a central database which stores vital settings & options for your computer. Unfortunately, this database is being used so much that your computer is constantly being unable to read the files & settings that it needs to from it, leading your computer to run much slower & with a lot of problems. It’s often the case that damaged registry settings will cause your PC to load up a lot of errors & other problems… making it essential you keep this part of your system clean & secure. To do this, you should download a registry cleaner and repair any of the errors it has inside. You can see our recommended cleaner below:
