Issue Details

I installed the IVI driver for my third-party instrument (a Rigol DM3068 digital multimeter) and configured the IVI Driver Session in MAX. Then, I added a IVI Dmm step in my TestStand sequence to configure the device. When I ran the sequence, I got the following error:

An error occurred calling 'RunStep' in 'ISubstep' of 'zNI TestStand Ivi Step Types'
An error occurred while executing the step. 
Component Works IVI Control Error: The IVI Init operation failed for logical name 'Rig'.

To troubleshoot the error, follow the steps below.
    1. Ensure that the IVI driver session was properly configured in Measurement & Automation Explorer (MAX) by referring to Using Measurement & Automation Explorer to Configure Your IVI System.
    2. In MAX, select your IVI instrument driver by navigating through the Configuration tree: IVI Drivers » Advanced » Instrument Driver Software Modules » <Your instrument IVI driver name>.
    3. Click the General tab and make sure the Module Path (32-bit) and Module Path (64-bit) fields point towards the correct location of the IVI driver dll installed on the PC. If the path is incorrect, click to the Browse… button to navigate to and select the dll.
    For example, the screenshot below shows the incorrect path for a 32-bit dll. For this 32-bit dll, ensure that Module Path (32-bit) is pointing to C:\Program Files (x86)\IVI Foundation\IVI\Bin\rgdm3k_32.dll  instead of  C:\Program Files\IVI Foundation\IVI\Bin\rgdm3k_32.dll.
