I have been unable to install Starfleet Command - Gold. When I attempt to install it I receive the message insufficient disk space and I have more then enough free space.

I am running Windows 10. I have already tried installing as administrator with the same result.

Can you help?

***Solved*** Running as administrator, defragmenting my hard drive and deleting the Star Trek Star Fleet Command folder from my GOG subdirectory allowed me to successfully install the game.
