Cannot delete Steam, path leads to wrong disk
Can you make a symbolic link from missing Steam directory to the actual one at D:
.
mklink /D "C:\Program Files (x86)\Steam" "D:\Program Files (x86)\Steam"
The method avoids downloading other utilities and uses the included functionality of the operating system
