Hello Uddesh,
As far as driver compatibility with your PCI-6014, yes NI-DAQ 6.9.3 can be used. However, it is recommended to use the most recent driver which is NI-DAQ 7.3 for most operating systems. The only operating system that requires 6.9.3 is Windows 95. Here is a link to where you can find all the drivers supported for your specific card and operating system
Driver Versions.
You could locate a newer manual in the following

Now, I am not sure who you talked to before regarding this issue, but I am not sure what examples you are referring to in specific and what you are trying to do. I would really appreciate it if you could post the details of the issue so that I can address your questions.
