After moving my matlab license to a new computer, I'm unable to connect to instruments with tekvisa and instrument control. The most obvious error is that instrument control toolbox hangs when I scan for instruments through visa. I have also seen this exception: Exception: PRIVATEFINDHWINFO returned unexpected results or errored out.
Communicating directly with the instrument with a non-IVI driver works. I can also use the tekvisa "OpenChoice" tool to communicate. This is all tested with a Tektronix MSO4104 oscilloscope. I have installed the latest tekvisa and IVI shared components. I use Matlab R2015a with Windows 10.
