There was that update glitch a few weeks ago, always prompted for updates...had to go in and delete all the files in the update folder except one of them...I don't remember the details, but it solved the issue.

If you have states installed that you wont be using, you can remove them in Windows Add/Remove Programs, choose ProSeries 2018 then it will ask you which part to uninstall and you can choose the states that you don't want.
