Missing dll file

Attempting to start system and this message appears after the sign in
screen on Win7

"There was a problem starting C:|Windows\system32\nvspcap64.dll"

Another longer message in a sseperate box said
"z:\Users\xxxxxxxxxxx\Desktop refers to a location that is
unavailable........"

Doing a search using Everything I found that the missing file exists
in several places on the computer, either on C or Z.
(Z is my SSD for data.)

I do have a clone of the system that is a couple of months old and
wonder if I would copy the missing file from the appropriate folder of
the clone and copy it to the current drive in use.

Would this solve the problem?

Thanks for any help.
