‘R6025 pure virtual function call’ is a runtime error that occurs suddenly on the screen and disrupts the program being run prior to it. This error display indicates that the program has been corrupted. R6025 runtime error usually occurs with the Visual C++ framework.
Error CausesThis error occurs when the C++ program crashes which is usually because of the malfunctioning or missing of the device driver or incomplete device driver files.
It happens because your application indirectly calls a pure virtual member function in a context where a call to the function is invalid. Most of the time, the compiler detects it and reports it as an error when building the application. R6025 error is usually detected at run time.
To fix the R6025 pure virtual function call error, you need to find the call to the pure virtual function. After you find the call, you need to rewrite the code so that it is not called again.
There are 2 ways to do this:
One way to fix the R6025 pure virtual function call is to replace the function with an implementation that calls the Windows API function DebugBreak. The DebugBreak causes a hard-coded breakpoint.
Once the code stops running at this breakpoint, it is easy for you to view the call stack. By viewing the call stack you can identify the place where the function was actually called.
Another quick way to find a call to a pure virtual function to fix the R6025 error is to set a breakpoint on the _purecall function that is usually found in PureVirt.c.
By breaking this function you can trace the problem occurring and rewrite the call to ensure the error does not occur and the program you are trying to develop on the Visual C++ framework is easily developed.
If R6025 Error is related to Windows Registry Problem Then here’s how you can fix the problem:
To fix the runtime error R6025, run registry cleaner software to scan and fix all errors. This alternative is suitable if the R6025 error is related to the Windows registry problem and where the error has occurred due to corrupted or malicious registry entries.
You can download the registry cleaner repair tool for free. Run it to scan errors and then click the fix error button to repair the problem immediately.

This occurs when the Windows Firewall service is missing. The service doesn’t start due to permission errors on various registry keys. It is a critical blue screen of death error code that turns the computer screen blue and causes the Windows to shut down. If this error code is not fixed it may start appearing more and more frequently resulting in total system corruption.“There was an error opening the Windows Firewall with Advanced Security snap-in. The Windows Firewall with Advanced Security snap-in failed to load. Restart the Windows Firewall service on the computer you are managing. Error code: 0x6D9”

Error Code 0xC1900101, 0x4000D is not very common among the many error codes emerging when updating to Windows 10. It is specific to Windows 7 users who try to upgrade to Windows 10 system.
This error hinders Windows 7 users to install the Windows 10 update. Once the update is launched, the process will go smoothly until a certain percentage (normally upon hitting 70% or more) and then it gets stuck. The user will then see a notification stating: “The installation failed in the SECOND_BOOT phase with an error during MIGRATE_DATA operation.”
You’ll be able to get past the error after a while. The error message will disappear and continue with the configuration process. But, not for long as it will reoccur at around 90% of installation with another error message saying: “The installation failed in the SECOND_BOOT phase with an error during PRE_OOBE operation.”
Error CausesYou’re most likely to encounter Error Code 0xC1900101 – 0x4000D when you upgrade to Windows 10 using a USB drive. There are several reasons why this update-related error happens such as wrong update, incompatibility with an antivirus program, or incompatibilities with some software.
In attempting to fix error code-related problems, it is best to do manual repair methods. Employing repair methods manually can help users pinpoint the root causes of the issues they are encountering and apply permanent solutions to fix the problem.
While every Windows user can do most manual repair methods, there are certain cases where help from a Windows expert is needed. If you’re not confident in employing the manual repair methods yourself, you can always consider seeking help from a professional Windows technician who is equipped with enough knowledge to address any issues you are facing or you can just simply use a powerful automated tool.
In fixing Error Code 0xC1900101 – 0x4000D, you can try doing any of the following manual repair methods:
Error Code 0xC1900101-0x4000D probably occurs when there are programs running in the background of the system as you are in the process of updating. On that note, you must ensure that any programs running in the background must be disabled through Task Manager.
NOTE: If there are any processes you are unfamiliar with, you can always right-click that process then “search online.” Be careful not to end “Windows process” tasks under the “Type” column as it might cause further problems.
Anti-malware tools normally trigger problems since they consist of files that are possibly incompatible with some software. If Error Code 0xc1900101-0x4000d is caused by incompatibility with an antivirus program, follow the following steps:
In doing this method, you need to use the System Readiness tool.
NOTE: The process might take a while depending on the speed of your device.
Can’t seem to put up with the long and technical manual repair process? You can still fix this error by downloading and installing a powerful automated tool that will surely get the job done in a jiffy!
