Error - session handle nor valid for ivi

[LV_user1]

Hi All

I have posted this question in existing thread also I guess.

 I am trying to control TDK lambda power supply through LabVIEW using IVI drivers.

logical name set in a MAX is same as what I am giving in VI to InitializeWithOptions.vi . However I am ending up with this error "IviDCPwr Initialize With Options.vi<ERR>
Primary Error: (Hex 0xBFFA1190) The session handle is not valid."

Not sure why this error is coming.

 Can anyone help me with this error?

You might be using an IVI-COM driver and trying to use IVI-C Class driver VIs without having installed the IVI-COM adapters.

As mentioned in the knowledge base below The IVI-COM adapters are included with IVI Compliance Package 3.2 and later, but must be enabled in the installer's feature tree.

IVI-C Class Driver Support for IVI-COM Specific Drivers

Hi

Thanks for the reply. From where exectly I ahve to enable it in installers feature tree? I am not able to find it..

Also how can I come to know whether i am using IVI-COM drivers or IVI -C drivers.

From MAX when I ahve configured I ahve selected IVI- C drivers only.
