I have the same issue..Do you know ultimately what happened and how to fix?

@ZACHOCALL - Have you tried the FORCE install?

@George4Tacks Yes, it will not install that way because it says it cannot communicate with Lacerte (for the download I assume)

@ZACHOCALL Do you have an anti virus? What are your firewall settings? Unfortunately I believe you need to call support. Please post your solution here, if you can.

@George4Tacks I did call support, the problem is that Lacerte has recently changed the ports and IP addresses it uses to communicate to a much wider range of addresses.  Lacerte has failed to updated it's Configuration settings within Knowledge Base article : https://accountants-community.intuit.com/articles/1861054-firewall-and-anti-virus-software-configura...

Sad to lose a full work day to this but I am glad we have resolved it.  We had to check the firewall logs to see what new addresses were being used and add them to our safe list withing the firewall.  

Thank you for sharing with the community.
