How to establish connection issues when installing devices

I currently have the latest Microsoft operating system installed on my computer and I attempted to add another driver for one of my external devices. I am always prompted with the problem that the system cannot establish a connection to the desired drive location of the file.

Hence, the program cannot be added. I went ahead and contacted the customer support of my device driver manufacturer and they gave me solutions for Windows settings, which I found that, were already in place. I even tried the built-in problem solver in my computer but the problem still persists. The manufacturer does not want to help anymore and they are insisting that it is not their issue anymore.

Can you please give me advice on how to move forward with this? How can I add this driver without getting an error?

Thank you.
