Solution for failure to open files and adding files to projects through vc6.0

When I was developing with VC today, after creating two classes, I found that the class view is not displayed in the file, so I want to manually add these two classes to the project. I did not expect a memory read/write error when I add a file. I thought it was a software error. After the software was restarted, it was still the same. Then I found that I couldn't open the file even from the "file"-"of VC, similarly, a memory read/write error is reported. After being depressed for a long time, I thought it was possible that I was poisoned. I started to look for software for anti-virus and found that the same error still occurred.

So I finally found the information on the Internet after finding it for a long time. It turned out that there was a conflict between vc6.0 and Visio. It was really hard. It was Microsoft's stuff and there was a conflict, uninstall Visio and solve the problem completely. I really don't understand. My own software runs on my own platform, and my own people are still fighting, so I can only say it's speechless.
