Why when I install Visual Studio 2017, change the path to drive D, install, and all files are installed to drive C?

Question

visual studio

the fact is that I have very little space on the C drive and I try to install all the files on the D drive, after downloading the Visual studio client, it offers me to download the individual components that I need, for example, compilers, a set of tools, etc.
after I chose everything, it says not enough memory to me, although I chose 25 GB and I have 133GB on the D drive, after which I just installed Visual studio without components and realized that all the space was taken up on the C drive.

Answer 1

Because many libraries that are needed for work are installed on the C drive.

Answer 2

updated apparently, instead of installing from scratch, check the daws again carefully - it definitely can not be set to C
