Install digital signature certificate: Go to the Microsoft download center and download the root certificate updates for Windows. Install the certificate updates and restart your computer. After the restart, try downloading the update again.

Repair QuickBooks installation: If none of the above steps resolve the issue, try repairing your QuickBooks installation. To do this, go to the Control Panel and select Programs and Features. Find QuickBooks in the list of installed programs, right-click on it, and select Repair.
