Andywomack do you have any idea as to a timeline for a 100% fix for the Sage 50 2020.1 update?  All workarounds and fixes to date are unsuccessful.

Andywomack do you have any idea as to a timeline for a 100% fix for the Sage 50 2020.1 update?  All workarounds and fixes to date are unsuccessful.

This is the latest and should work now: cdn-dlm.esd.sage.com/.../SA_20201CPUP1.exe

When i update the sample company, it fails always at 9/30 with "cannot open file", even with the download you provided above.  I am SUPER hesitant to work with live files if the Sage provided sample company fails to update properly.  i don't know what else to do?  My clients are pretty much at the limits of patience.  We do these updates all the time - i don't understand why this one is so difficult.... 

See the posts by Jane Sun above, the work around seems to be:

1. Copy the SAI file and the SAJ folders to somewhere on your C: drive (or I'm guessing any "local" drive that you have full permissions to would work as well)

2. Run the database update against that local copy - it should get all the way through.  It probably would be best if you were logged in on the computer as a "Local Admin" as well, or if you are in a Windows Domain logged in as a Domain Administrator, and when you start Sage do it "as Admin" (i.e. instead of simply double-clicking your Sage program icon, right-click it and choose "Run as Admin")

3. If the database update finishes, I would first test trying to open that local copy of the company database

4. Copy back the updated SAI file and SAJ folders back to their original locations (first rename the old SAI and SAJ so there are no naming conflicts)

I was able to successfully upgrade a copy of my production database up to step 3 yesterday.  I plan to try the full process today as tomorrow we need to run payroll.

Hi Joe,

Thanks for the reply.  I tried that and as soon as I start to open it I get a 'required data file is missing' error. 

Were all your users logged out of Sage when you copied over files?

I think I would verify that you really did copy over all files, one way would be right-clicking the SAJ folder and choosing "Properties" and noting the Size and the Files and Folders count.  Then check if that matches the copied over folder.

Also, make sure you are an "Admin" on that machine, as all these troubles smell like permission issues to me.
