Your message isn't clear.  For #1, you say NI-VISA is installed/LV needs VISA.  Did you mean to day NI-VISA is NOT installed?  If something is installed, and needs it, there should be no error.

 

For #2, what is the "emant300" driver?    Is it trying to use the com port at the same time as LV is?

 

Do you have any error codes or clear description of the error?  A screenshot?

From that error message it sounds like some part of the VISA driver set is missing.

 

The EMANT uses a virtual serial port through USB.  It has been a while since I used one, but I think it uses the FTDI device.  You need the USB driver for that ( a .dll, I think) and the VISA serial functions.

You need the hardware driver for the serial port called NI-VISA. The error message clearly says you don't have it Download from here.

 

You should review all of the 'Learn to Use Instrument Drivers' links on the main Instrument Driver Network page.

Dennis said it clearly.  You need to have at least three different software components installed on your computer: LabVIEW, NI VISA, and the EMANT software.  Do you have all of these?
