How to check if NI-Scope or NI-VIsa driver installed

[Fedor]

I would like to check if NI-Scope and NI-Visa are installed on the PC before loading relevant parts of the Labview application. There's an example of checking for NI-DAQmx, which I implement with slight improvements:

Any advice what to check for in case of  Visa and Scope drivers?

Hi Fedor,

You might be able to use the method described here for VISA:

And for the scopes (and any other modular instruments) you may be able to use this:

Hi Mada,

I indeed use the methods you've listed to scan for available devices in my application. What I'm trying to find is if there's an established way to detect the presence or absence of the software drivers such as VISA, NI-Scope etc. before attempting to load corresponding parts of the application. Otherwise the application will end up broken.

Hi Fedor,

I believe this might be the method you are after then instead:

Hi Mada,

I did try that too a while back, it required system configuration driver to be per-installed and breaks the application if nisyscfg*.dll is missing.

For now I just use the same approach as in my 1st link and look for presence of niscope* or nivisa* in the system folder.

In that case, it might be the best method for now.  I have looked very thoroughly for other ways to do it, but I can only find that solution so far.
