How to Completely Uninstall QuickBooks

Intuit's QuickBooks is a line of business accounting software, released not long after the commercial success of the Quicken line of personal accounting software. QuickBooks has since become the premier business accounting software, with "USA Today" stating that it commands 87 percent of its market. Despite its popularity, QuickBooks isn't immune to occasional problems that may require a reinstall. A complete, or clean, uninstall is the first step, and one of the most crucial.
