Jeff, we have many clients in the health care field as well as municipalities, their security levels are low and they do not have administrator privileges on the machine, this solution is not suitable for us, but thank you for the suggestion.
Concerning the deployment of differents versions, we already deploy our solution to our customers using "web update". It's not a big thing for us to deploy a support tool within our application. But I understand your point of view Bigdessert.
