official driver not executable ?

[achouch]

Hi, 

I am using a (Rohde und Swartz HMF2525) Funtiongenerator  and I am controlling it from LabView, I installed the driver from the official website https://www.rohde-schwarz.com/de/treiber/hmf2525/

it was working perfectly but I don't know why it is not working anymore; it keeps showing the error 'not executable' in every VI I test ...what could this mean..?

Not executable means there's some error preventing execution. 

Use the error list (Ctrl+L, or click the broken run arrow) to see what the errors are.

I just downloaded the LabVIEW 2010 driver hmf2500 from that page unzipped it and I don't get the broken arrow opening the Initialize iv

Tell us the error you are getting that makes it unexecutable

Sometimes a Mass Complile can fix this if the problem is one of the libraries is not linked properly.

I recall the MS Office toolkit had some issues linking to the .NET office interface - this was dependant on your particular labview install.

Performing a Mass Compile, or simply - going on the diagram and selecting another pulldown from the .Net or VISA ref...then selecting it back ...would instigate LabVIEW to initialize the library/interface call...

Worth a try.

I didn't download the driver to check it, but here are some options (in addition to what others said):

-Did you open and modify one of the VI's, possibly breaking it? Try reinstalling the driver.

-Does the driver need a DLL? If so:

     -Make sure the DLL is in the same folder as the VI calling it

     -Make sure your LabVIEW bitness matches the DLL bitness (32 bit vs 64 bit)

At any rate, we need to know what the error is. Click the broken Run arrow and it'll tell you what the error was.

Even when I open that in a new tab, the resolution is far too low to read it. Can you copy the error code and source text and paste it here?

Here is a Windows tip:  Reduce the size of the front panel to just the size of the controls, then hold Alt before you press Print Screen.  This will only capture the topmost window.

A VISA Read error? So the driver IS EXECUTABLE?

BTW: A non executable vi will have a "Broken Arrow" instead of a solid Run Arrow.

I am guessing you don't have the VISA resource set properly.
