Occassionally there will be issues with any product. William English received the following question.
Q: I have a customer that is having a problem with her POS client crashing when she tries to load it. It starts checking the licenses and some time during that process it encounters an error and crashes. I have reinstalled the dot net updates and also reinstalled the POS using a separate license. still having the problem.
His answer was: This is a problem with a firewall blocking the entitlement client. If you are using Norton, the problem is worst as just turning off the firewall will still leave components in place. If you are using a hardware firewall (most routers and modems include this) there is no reason to use a software firewall beyond Windows firewall and even then it is not needed. This is a firewall permissions issue. In Win 7, we have gotten it to work by adding the IP and computer name to the hosts file. If you are using any firewall other than Windows, all bets are off.
