Do you have Visual Studio installed? If you do, you may have to set some variables as explained here.

Yes, I installed Visual Studio this is what the variable looks like and the Visual Studio version is 16.7.7

[Andreas Papacharalampous]

The variable value should only include the path of your installation, remove "set vs2018_install=" and leave the path intact.
