We recommend you download the most recent version (1.4.0.0) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've already installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be displayed on the bottom right or you can select About to view the version. Open the file you downloaded (QuickBooksToolHub.exe). Follow the on-screen steps to install and agree to the terms and conditions. When the install finishes, double-click the icon on your Windows desktop to open the tool hub. Step 2: Use the QuickBooks Install Diagnostic Tool Open the QuickBooks Tool Hub. In the tool hub, select Installation Issues. Select QuickBooks Install Diagnostic Tool. Let the tool run. It can take up to 20 minutes. When the tool finishes, restart your computer. Step 3: Update Windows Window updates prevent and often fix install errors. Check out Windows Update: FAQ on how to update your version of Windows from Microsoft, Once the update finishes, restart your computer. If you could open QuickBooks before you saw the error, Open QuickBooks and your company file. If you weren't able to install QuickBooks, install QuickBooks Desktop again.
