Recently, because of project needs, I plan to try to develop in Visual Studio, which is very annoying. Error messages will always appear during the installation process 您尝试安装的产品版本比此计算机上已安装的版本低. Obviously, the message prompts you that a higher version is already installed on the computer and the relatively old version cannot be installed. Because this time I plan to install the Visual Studio Community 2015 version, through uninstallation and registry deletion, after I think it has been uninstalled cleanly, I still continue to report this error message.
It seems that this uninstall method does not completely uninstall the old version of Visual Studio. Then consider the uninstall tool.
Here is a tool for completely uninstalling Visual Studio, VisualStudioUninstaller . After installation, right-click the administrator to run it to uninstall all.
