"Error -1073807202 : A code library required by VISA could not be located" When Communicating With Serial Ports

Primary Software: LabVIEW Development Systems>>LabVIEW Full Development System
Primary Software Version: N/A
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
Why do I receive error -1073807202 : A code library required by VISA could not be located when communicating using the serial ports on my system?

Solution:
This error could occur because of the following reasons:

NI-Serial or NI-VISA Software need to be repaired
The earlier versions of NI-Serial (earlier than 1.6) would occasionally cause an error during reinstallation. When trying to run the program after doing a reinstalltion, this error could occur. The solution in such a case would be removing the software completely from the system and doing a reinstallation or upgrading to a newer version of the software
NI-VISA not installed in the system at all
NI-VISA is required if you want to communicate through the serial port using LabVIEW.
Visa32.dll missing
This DLL should be located at WINDOWS\system32. If this DLL is missing for some reason, this error could occur. Copy the DLL from some other system when serial communication is working fine and place it here.

Note: NI-VISA can be obtained from the Drivers and Updates page.
