RAD Studio Installer Error - Part 2

RAD Studio Installer Error - Part 2

The saga continues. I was given instruction from the support team to launch setup.exe from the install folder of the 10 Seattle Update 1 ISO.

I have 333GB available on the C: Drive

Now the Embarcadero RAD Studio 10 Seattle InstallAware Wizard says I have Availabe Disk Space:  -1 bytes

This is killing me here.
