This is the installer of the build tools from Microsoft (i.e., this is all that is tedious to build projects but without a development environment, without an IDE). If you need with a development environment, then install this

More specifically, unlike the full studio, this installer does not include the VS IDE Core component and, accordingly, you cannot install the visual development environment through BuildTools. Through this, an attempt is made to reduce the weight of the installer and reduce the size and impact on Windows. BuildTools does not provide any additional features (that is, it is like a "toolchain from small soft" ... it seems to me it would be worth calling this modification so that everything was clear at once ... but apparently the desire to be unique and inimitable prevents them from using calmly already available terms ).

Installation:
• Disconnect from the Internet ... so that the installer does not download the lists of installed components for the most recent version ... the one that may not yet be available in the distribution. If this happens, then the installer may no longer have enough of what is in the distribution and download errors may appear
• If the installer does not have access to the Internet, then install certificates for self-diagnostics of the installer by executing Certificates_Setup.cmd
ON BEHALF OF THE ADMINISTRATOR • Then run Setup_BuildTools . cmd, where X specifies the version number you want to install (i.e. 16.7.X)

.NET Framework 4.5 is required to install Visual Studio. Visual Studio requires .NET Framework 4.7.2, which will be installed during setup.

Learn more about the problem with updating studio
If you encounter a problem with the update, to begin with, you can try to simply restart the update process (i.e., pause the update, restart the installer and resume the update). If it doesn't help, then try the following.
If you remember the name of the folder from where you installed the studio, then make sure that the installer from this distribution starts from the folder with the same name (rename / move the folder or, it's easier, make a symlink ... if you can of course). If you don't remember where you installed it, then before updating, you better save your component configuration to a file, so that if the update breaks off, you could move the studio from this distribution with less effort using the saved component configuration (when reinstalling, you do not have to select your components manually).
In order for the installer to first ensure the availability of everything you need, and then start the update procedure, you need to refuse the automatic update offer, and update through the additional menu item "Download and update". Otherwise, you may get stuck in a situation where some of the old components have already been removed, but new ones have not
been installed instead.If you have access to the Internet, then this problem is not particularly critical for you (just some of the components that the installer will see on the disk will be downloaded from Internet).
