For some reason, sometimes Visual Studio 6.0 (vs6) cannot be automatically uninstalled. In this case, you must manually uninstall Visual Studio. Otherwise, the re-installation of vs6 may fail. This article describes how to manually unload vs6's documents in detail in http://support.microsoft.com/kb/248#/en-us (For WINXP) As follows:
1. Confirm the latest necessary components of the system and try to delete relevant programs
(1) confirm the latest version of vmhelper. dll: This is a Java Virtual Machine. Compare it with the version on other machines. If not, copy one.
(2) confirm that Microsoft Data Access Components (MDAC) is up to date. XP is integrated with mdac2.8, which usually does not require installation. If you are not at ease, download SQL Sever 2000 Chinese Personal Edition (Chinese edition is installed in the Chinese operating system) and then install SP4. During the installation process, pay attention to the prompts and select according to the specific situation of your system, do not click Next all the way; otherwise, an error will occur.
(3) If you can, uninstall msdn and vs6 and their related products through the Add/delete programs on the control panel (restart each time a product is uninstalled ), in addition, you can also delete the related vs6 plug-ins (such as MZ-tools) installed by yourself.

If the registry is cleared, I have tried intelligent uninstallation by wise registry cleaner and Windows optimization masters before. HoweverRegistrar Registry ManagerThis tool is quite useful. You can directly Delete the found keys with Visual Studio at one time. However, it is recommended that you do not use this tool because you may have deleted some files that should not be deleted. The best way is to follow this document and delete them one by one.
3. Delete related folders and files
(1) Delete the following folders:
- C:/program files/Microsoft Visual Studio(Or the directory where you installed Visual Studio)
- C:/program files/common files/Designer
- C:/program files/common files/Microsoft shared/Msdesigners98
- C:/program files/common files/Microsoft shared/Msdn
- C:/program files/common files/Microsoft shared/Triedit
- C:/program files/common files/Microsoft shared/Vs98
- C:/program files/common files/Microsoft shared/Wizards98
- C:/Documents and Settings/your login/Application Data/Microsoft/Visual Studio
Note: C:/program files/common files/Microsoft shared/The triedit folder cannot be deleted in unsafe mode. Remember to delete it after entering safe mode.Otherwise, the installation process will report the following error: wpie15.exe application error, the memory cannot be read (sometimes the memory cannot be written); or the error: Win32 cabinet self-extractorin case of a problem, the appname in the detailed information is wpie15.exe.
(2) Delete msdn: in this article, refer. If there is a problem with the installation, you can try it.
(3) Delete all files in your temp directory (typically, "C:/Windows/Temp"). Check the environment variables to check the directory location.
(4) Clear the recycle bin, restart the system, enter the security mode, and log on with the administrator account. Then you can install the new vs6.
