The R6025 error is a big problem for Windows computers which is caused by the Visual C ++ Runtime Library either being corrupt or damaged. The problem you're seeing is that your computer is basically unable to read the files and settings it requires to run a particular "function" for a piece of software on your computer. If you're seeing this error, it generally means that your computer will not be able to read a specific "Pure Virtual Function Call" that you've either put into a program, or you will be using a piece of software that has this problem inside.
The error which will be showing on your PC will typically show in this format:
- "Error R6205 – Pure Virtual Function Call"
The problem is that your software is trying to incorrectly load up a pure virtual function, meaning that whenever you use that software, it will be able to process the settings required – leading the errors to show. The way to fix this problem is to either change the software you're developing, or to fix any of the settings / problems which may be causing the issues inside the Windows system.
The way to resolve error R6025 is to first ensure that your software is running fine – which means that if you're a developer, you need to be able to fix any of the errors inside it, and if you're a general user you should re-install the program. This can be achieved by first clicking onto "Start> Control Panel> Add / Remove Programs" and then removing all the parts of a piece of software that's causing problems for you. Once the software has been removed, you need to then restart your computer and then re-install the program from the installation medium (such as a CD / DVD).
Cleaning out the registry of your PC is also recommended to fix the R6025 error. The registry is a central database which stores all the settings of Windows – and is where the likes of your desktop wallpaper and even your recent emails are kept. Despite the registry being a highly important part of your computer, it's constantly causing a large number of problems due to the files & settings of it becoming damaged and corrupted. To resolve the issues you're seeing with this downloading a registry cleaner from the Internet, installing it and then letting it resolve all the damaged settings, which should resolve 99% of these r6025 errors on your PC.
