Solution 6: Perform a Clean Install of QuickBooks

A clean install is usually done when one of the program’s features are damaged and need repair and also when the usual reinstall fails to provide any comfort or a solution to the problem. In order to start the installation process make sure you have the setup file you downloaded from QuickBooks’ official site. You will also need your license number before you start.

  1. First of all, make sure you are logged in with an administrator account as you won’t be able to delete programs using any other account.
  2. Backup the data you want to save because deleting QuickBooks will remove it.
  3. Click on the Start menu and open Control Panel by searching for it. Alternatively, you can click on the gear icon in order to open settings if you are using Windows 10.

  1. In Control Panel, select to View as: Category at the top right corner and click on Uninstall a Program under the Programs section.

  1. QuickBooks’ uninstall wizard should open with two options: Repair and Remove. Select Remove and click Next in order to uninstall the program.
  2. A message will pop up asking “Do you want to completely remove QuickBooks for Windows?” Choose Yes.
  3. Click Finish when the uninstalled completes the process and restart your computer to see whether errors will still appear.

The next thing in the process is to rename the installation folders so that QuickBooks does not use the remaining files after you reinstall it. This is an easy task.

  1. Navigate to the C >> Windows folder on your computer by clicking on This PC option located at your desktop.

Note: If you are not able to see some of the folders we mention below, you will need to enable the Show Hidden Files and Folders option from within the folder.

  1. Click on the “View” tab on File Explorer’s menu and click on the “Hidden items” checkbox in the Show/hide section. File Explorer will show the hidden files and will remember this option until you change it again.

  1. Navigate to each of the folders displayed below and rename them by adding ‘.old’ to their name. This means that the new installation of QuickBooks won’t use these folders or the files located in them.

C:\ProgramData\Intuit\QuickBooks (year)
C:\Users\(current user)\AppData\Local\Intuit\QuickBooks (year)
C:\Program Files\Intuit\QuickBooks(year)
64-bit version C:\Program Files (x86)\Intuit\QuickBooks (year)

Note: You may end up receiving the “Access Denied” error when you try to rename these folders. This only means that one of the QuickBooks processes is running and it prevents you from modifying any of the files and folders these processes are using. Follow the steps below to fix this:

  1. Use the Ctrl + Shift + Esc key combination in order to bring up the Task Manager. Alternatively, you can use the Ctrl + Alt + Del key combination and select Task Manager from the menu. You can also search for it in the Start menu.

  2. Now you are ready to reinstall QuickBooks Desktop by running the file you downloaded earlier. The link is at the very start of this Solution. Follow the instructions which appear on screen and check to see if the same error appears.

Alternative: If the clean uninstall doesn’t work for some reason, you can always try and repair the installation by choosing the Repair option in Step 7 of this Solution. After the process finishes, try to see if the error message still appears.
