How to Fix QuickBooks Desktop Error 1606 (Could not Access Network Location)?

QuickBooks Error 1606 stops the software from installing or updating because it cannot access a required network location. This happens due to incorrect network settings, damaged Windows registry entries, or a corrupt user profile. Security software interference and insufficient user permissions can also cause this issue. Many users face this error while installing QuickBooks, but it affects other Windows programs as well.
