Sage Construction & Real Estate

WHERE CAN WE FIND THE 25.1.330 SET FILE

I am new to Sage. We are trying to move Sage 100 Contractor to a new server. We have Deauthorized the old license server. When trying to update new license server, we continue to get error "Unable to update License information: failed to contact Sage…

Has or is anyone using windows 2019 standard server and running sage 100 contractor on it ? If so are you having issues ? Any suggestions or things not to do when deploying this?

Looking to update after closing year - is there a sequence to get up to date, or can I apply the latest version? Thanks.
