TOFO, your device's SSHD is probably full with redundant Win10 updates. When I first had a small laptop with similar limitations, I couldn't install Office 365 after Win10 had first update itself.
This was fixed by clicking the 'start' icon, then typing 'clean'. This brings up the option of running 'disk clean up'. Click on that and then on the bit which says 'Clean up system files'. When the music stops, you'll probably find several GB of redundant Windows Update stuff which you can delete - it takes a few minutes to run the clean up though.
