daq.Vendors returns 'Operational' attribute of 'mcc' as false

1 view (last 30 days)
I am using a MCC data acquisition hardware. I have downloaded the correspoding support package. But when I run the “daq.getVendors” command, the “Operational” column of the “mcc” row is “false”. I could connect to the device through MCC’s InstaCal utility. How could I solve this?

MATLAB Data Acquisition Toolbox requires certain version of MCC driver to work. And this particular version of driver is normally installed along with the support package. You might see that during the installation of the support package, it will tell you that a third-party software is downloaded, and that is the driver with the required version. But if you already have a driver, which could be any version, installed on your machine, the support package installation might skip the driver installation step. That will cause incompatibility, which might introduce unexpected behavior. 
 Please try the following steps and see if it helps: 
  1. Uninstall the support package. 
  2. Uninstall the MCC software. 
  3. Install the support package again, and the right version of MCC software will be installed along with it 
  4. Restart machine
