When updating VISA drivers from 3.3.1 to 3.6 is it necessary to delete the previous 3.3.1 driver or does it not matter having both 3.6 and 3.3.1 existing together.
Just a small technicality I want to get out of the way.
Thank you for contacting National Instruments. You do not have to remove NI-VISA 3.3.1 prior to installing 3.6. NI-VISA 3.6 should upgrade
properly over NI-VISA versions 2.0.1 through 3.4.
