Not enough disk space for admin image

Hi,

I'm trying to create a new admin image on a new server, but every time I try, I get the error:

There is not enough free disk space on K:\ to create the administrative image.

Total space needed: 8.5 GB

Space available: -2047 GB

Free up space (-2038 GB more required) or select another drive.

This condition must be resolved before you can continue.

It will install if I point it to the 300Gb C: drive so I know the install is working, but I don't want it on the system drive.

The data disk on this server is a 4Tb disk, so I'm guessing there is some max size that solidworks looks at, and then gets thrown into a loop if it's over that?

Any way around this to install the image to my large disk?

Thanks
