Sage 50 Canada

We purchased Sage 50 Premium 2017 back on November 4th 2016. It was licensed to our company. I have the serial number, the account ID, the key code and the invoice from Sage giving us the download link, etc. We were allowed to have it on 2 computers so…

I received an email with an update from Sage 50 2017 to 2017,1. When I try to install I am prompted to uninstall my existing version before installing the new version (update?). Is this necessary and not included in the instructions?
