The file is downloaded.
This file has the extension ". zip". Since the entity is a ZIP file, you can extract it and extract the contents.
After extracting the ZIP file, open the extension.vsixmanifest file in a text editor. Use Notepad, which can edit UTF-8 files.
After opening the file, look for the line "InstallationTarget".
Change the Version value in that row to 12.0. 12.0 is the internal version of Visual Studio 2013.
Save your changes. Then re-pack all the files you extracted earlier into a ZIP file. In doing so, make sure that all files are directly under the root. If you put a folder in one level, you will not be able to install it properly.
The extension is changed to ". vsix".
All you have to do is double-click to install it. You can see that the version of Visual Studio that you want to install is now 2013.
Close it when the installation is complete. Using Project Linker is the same in Visual Studio 2013 as in 2012.
