Instrument Assistant communicating with pressure gauge, but still getting Error 1073807246 after Win7 conversion

[cramezl]

I have a simple .vi that I have used for the last year to communicate with a pressure gauge. All it does is log and plot pressure over time. Our computers just got converted to Windows 7, and now I can't get the .vi to work. I can go into the Instrument assistant and send a command to the gauge, and the gauge will respond appropriately. But, when I run the program, I get no pressure information on my front panel or in my log file.

I've searched the error code, and tried several things, including http://www.ni.com/support/labview/visa/verr3.htm. I'm guessing it's a simple fix, I just don't know what it is. Help a beginner out!

Are you absolutely sure that you have closed all other programs that could be accessing the port? Having MAX open with a VISA test panel or an older version of LabVIEW would cause the error.

Pretty sure. It's a brand new machine. All I have done is install LabVIEW (basically all the laptop is used for) and attempt to run the .vi

What about any software from the vendor of the gauge? Anything shown in the services that are running?

I'm really not a fan of the instrument assistant. Have you converted it to a regular VI? If you create a new VI with just a VISA Open, do you get the same error? If you completely close LabVIEW and then open MAX, do you get the error when you open the VISA test panel?

You were right. :manembarrassed: Another tech had installed Digiquartz and I didn't know it. Had my com port all tied up. Thanks
