The Sage 50 2020.1 downloads have been replaced. See KB 100797 for the full product download and KB 102293 for the product update. Please remember that the hotfix for customers who have already downloaded and installed a 2020.1 update prior to today is available in KB article 102602.
We downloaded 2020.1 and have been able to open some companies but not all of them. It does the endless loop. I tried calling Sage but was not able to get through, told to call back. Is there another problem and if so is there a fix?
Something I discovered in my initial "failed" update is a log file that gets created in the SAJ folder of the company that I was trying to update. It's a text file that has is named with the date & time of when you ran the update. It gives a blow by blow entry for every step of the update, and you can pretty much tell exactly where things went wrong because of the error messages logged in there. In my case I could see it was having problems with connecting to the MySQL server (the amazing thing was seeing it try and fail the same thing over and over again - you would think they would write the install script that once a fatal error occurs, to stop trying at that point and report the error right away).
Anyways, that file might give you some clues as to where the failures are occurring. If you ever get through to support, I would think it would be something they would want to look at.
