If there are problems downloading updates in a Quicken application, such problems can be related to the internet connection, firewall configuration, or short-lived server congestion. The first thing that you may do is make sure that your internet is still available and you have a good connection. Troubleshoot any internet problems. In case of the absence of any internet issues, go to the firewall and antivirus settings, as they may prevent Quicken from accessing the server. Turning them off temporarily may assist in identifying their effects.
If the internet is found to be working, you may try updating your Quicken version once more from the “Help” menu by selecting “Check for Updates.” If this does not succeed, you can go to the official Quicken website and click on the downloads section for the update of your particular version. Before the action-updating takes place, ensure that Quicken is opened in administrative mode by right-clicking the program icon and selecting ‘Run as Administrator.’ This is quite helpful, especially where the update was not successful due to changes in permission settings. If all the above steps do not help, you may need to contact the Quicken support team for more advanced assistance.
