Unity installation low space error problem

hi, I downloaded “unity hub 2.4.3.0” and installed it in my D drive, my C drive is low in space. Now I opened unity hub and went to installs and when i try to add a version (Recommended release Unity 2020.3.8.f1(Lts)) i get an error “There is not enough space to download and install the selected items”.
My D drive has over 400Gb free space.
Why this error is popping up while my unity hub is already installed in D drive.
I went into unity hub settings and in Unity editors path selected the same folder where my unity hub is installed.

Please need help.

To fix this you can change the location of your TEMP folder temporarily to install the Unity version you are wanting. Change the TEMP system variable to be set to the location in a folder on the drive that has the most space.
