This was the sort of issue I was getting with the drivers.
I tried multiple installs and reinstalled without success.
This was a new laptop with windows 10 and latest security updates. Switching off the virus checker did not work either.
I think the Sdrplay team need to seriously look at the installation methodology and process. A second point is Linux is extremely difficult and near impossible without spending hours and still then fail.
This could be a great product if only the driver installation was not such a problem.
