NI VISA driver was working fine until I installed a Tektronix driver .It threw the following error from then on
"1073807343 ERROR NI VISA write in"
So I uninstalled the NI VISA driver to install the new version with the bug fixes .
But I was not able to install the newer version NI VISA 14.0.1 as throws the following error
"
Unsupported version of NI-VISA detected
A version of NI-VISA that is not supported on this operating system has been detected. You must cancel this installation and uninstall the older version before continuing. Visit ni.com/info and enter the Info Code CleanVista for more information."
But I have uninstalled the older version already . How do I fix it ?
