I think I need drivers for my Win 7 64bit P.C to operate the unit as I cannot see when plug in via USB
The drivers, made for older windows versions, won't work on a Windows 7 or Windows 8. Not even in compatibility mode. Microsoft needed to make Windows more secure, so only allows drivers in there modern operating systems when they have a Microsoft certificate. For a certificate the manufactures must use Microsoft protocols, ask Microsoft for certification, and pay for the tests Microsoft does, to check the software is working correct. So no manufacturer will ask for certification of drivers for hardware they no longer sell.
Long story, but unless you can write your driver yourself, or you can find an universal device driver (not sure something like that exists) you won't be able to use the device.
I saw some dodgy sites trying to offer drivers. Be aware all drivers you can install in windows 7 or 8, you can get them from Microsoft. The ones you could use on an XP computer can't be used, because Windows 7 or 8 won't let you install them. Just for security reasons.
When your device is sold with compatible with Windows x and it is lower version then the one you use, most likely you can't find driver for your device for the modern Windows. Almost no manufacturer will offer drivers for hardware they no longer sell.
