Windows 11 Pro, Quicken version: R51.12, Build: 27.1.51.12. I have 3 Quicken data sets. The smaller 2 data sets "One Step Update" without a problem. The larger data set, however, will not update with all the accounts selected or even on a one by one account basis. It would normally take about 2-3 minutes in the past for this data set to successfully update, however, since Sept. 1, the update screen would be showing for days unless I control-alt-delete and end the task for the Quicken process. I validated the data set and no errors were discovered. Any suggestions?
