Ashish,
Thank you for your reply. GetVersion was returning the version of the run-time environment package, as was stated in the documentation you pointed me to. Thank you for that, by the way. I couldn't find that documentation before.
I tried to use GetInfo, but that didn't seem to give me what I needed either. GetInfo seemed to give the version of all of the files that were installed from the run-time environment package, but not the installed device driver version. I then used GetInfoEx, and that gave me the version of the device driver itself, which is what I needed.
Thank you for your prompt responses and informative answers. I now have the information I need.
Thank you very much,
Pete
