Solved!
Go to solution

Hello,

 

I need to launch a program (vibrometra) from labview. In the attached image it is possible to see the command line that I am using. In the path i am specifying the location of the executable file. 

I have checked that it is possible to open vibrometra program using this path with the "Run" window.. 

So I don't know what should I write in the command field..

 

Thanks in advance for your help!

Is that error a LabVIEW error or an error in the system exec window?  The LabVIEW error 87 is a variant conversion error, which does not make since to me.

Do you have a space in cmd/k (correct: cmd /k)? Though without space LV2011 gives me error 2, not 87

Also do you need to open command window (cmd)? I usually specify full path (path and exe name) as a command, no problem. Working directory is not requred then.

 

Edit: Full path in quotes not to have problems with spaces

"C:\Program Files\prog\prog.exe"

It was an error coming from labview. I am able to actually launch the program writing exactly the same full path in the command field (including file.exe).

Thanks very much for your help!
