Guys, thanks awfully for your help. I have now had a reply from the company a 'Fred' in China. He suggested that latter beta version as suggested by Bushfiva:
"RTL8187L Windows7 InstallPackage (Beta) version 1316(Beta)"
It still doesn't work.
I am reluctant to try a compatability mode. I am not that good with these things and with a band new computer I don't want to mess it up.
Another colleague has suggested that that the software on their site only works in the USA or Asia.
I have gone back to them and asked this question. Perhaps 'Fred' will come up with another solution.
In the meantime I have to keep working in the taverna above the office.
All other suggestions welcome. My bar bill is running up
Thanks again.
Kind regards.
EA
