Sage 50 2012 Service Pack 1 has been released. This service pack combines updates 1 through 3 with an additional update 4.
If your program version number is currently 18.104.22.168 or earlier you need to apply this update. Please check this in Help->About. If you have already applied updates 1 through 3, you can still install this service pack – it detects which updates are installed and which are missing. You can download the executable file for Service Pack 1 from here.
Before applying the update, backup your Sage data. Exit Sage and Microsoft Excel.
Your version number should now be 22.214.171.124.
