Hi. I was using a Window XP SP3 and a GPIB-USB-HS it was working correctly.
But virus may have damaged the software. I tried to reinstall to the driver but I am encountering the same problem over and over again.
On the 'Device Manager' the GPIB-USB-HS shows up that it was installed properly but on the 'Measurement and Automation' window doesn't.
I'm using a Keithley 2002 Multimeter and Wayne Kerr 4300 LCR Meter.
Thank you in advance.
