Rhinoceros 5 SR6 automatically installs on drive C

Hello Say how to change the Rhinoceros 5 SR6. I want to install the program on disk D, but during installation, there is no choice. In previous versions of rhino had a choice and I could install in any place. Help solve the problem.

Hi Aleksandr- there is a choice in the first or second screen during installation, near the bottom of the screen.
