Some hardware device drivers require system file support from Windows files. These are obtained through the Windows installation CD ROM, normally in the CABS files.
You could run a search for CABS using Windows Find and see if they are on your hard drive. Some system builders put a copy of your Windows setup files in a folder on the hard drive, often in C:\Windows\Options\Cabs or similar.
But no, Freeserve are ot obliged to make sure that you have a Windows disk or its setup files. That's down to you as the owner of your PC to supply the relevant operating system software.
Good luck with it
