Reinstall QuickBooks for Windows using clean install
When a QuickBooks Desktop function is damaged or when a simple reinstall does not correct an issue, you may need to uninstall QuickBooks Desktop for Windows, rename installation files left behind, and then reinstall the program. This process is called a Clean Install or Clean Uninstall.
On your keyboard, press Windows+R to open the Run command.
Type in Control Panel, then select OK.
Select Programs and Features (If Control Panel is in Category View, choose Uninstall a Program.)
In the list of programs, select QuickBooks, then select Uninstall/Change.
Follow the prompts to complete the process. Important: If you get an error message and are unable to uninstall QuickBooks, you will need to contact a qualified IT professional or Microsoft as this indicates there is a problem/corruption with your Windows Operating system (which is not an Intuit product).
Step 2: Rename the Installation folders
You have the option to use QuickBooks Clean Install Tool to rename the folders for you. If you do not want to run this tool, you can manually rename the QuickBooks installation folders.
Download and run the QuickBooks Clean Install Tool
Select your version of QuickBooks Desktop, then click Continue.
Click OK when you see the message "QuickBooks is now ready for a clean install, please install to the default directory."
Manually rename the QuickBooks Desktop installation folders.
Use Windows Explorer to display hidden files and rename each of the folder locations listed for your version of Windows. As a suggestion, add 'old' or 'damaged' at the end of the folder name. This will prevent QuickBooks from recognizing the folder in order to create a new one.
