Install errors with Invalid Drive

Trying to install DraftSight for a trial. I don't get a window allowing me to chose the install directory. I want to install it locally on my C: drive.

As a result, it tries to install on our network drive which I do not want and do not have write-permissions on. So I get this error message;

DraftSIght 2018 SP2 x64 Installer Information

Error 1327. Invalid Drive W:\\

How can I chose the install directory?
