I cannot open Handheld Contact on the Desktop - A message appears "Message Queue service is not available". How to fix?

When trying to open the Handheld Contact desktop application on the PC/server, you are unable to launch and the following error message appears:

"Unhandled exception occurred in Handheld contact!  Description of the error is: Message Queue service is not available." 

The Microsoft Message Queuing (MSMQ) component is essentially a messaging protocol that allows applications running on separate servers/processes to communicate in a failsafe manner.  This is configured and maintained via Windows and Handheld Contact just utilizes this feature.  If the service is not installed, running, or experiencing problems then Handheld Contact will also not work by association. 

Below are some tips on resolving this error message:

After uninstalling Message Queuing from the PC/server, a reboot is required.  When the computer restarts, follow the steps to re-install Microsoft Message Queuing.

If any additional error messages appear, please contact support with the exact error.

Note:  If the above suggestions do not work, additional assistance may be required by a Microsoft Windows technician as the root issue will be with the PC/operating system and not Handheld Contact.
