When a QuickBooks Desktop function is damaged or when a simple reinstall does not correct an issue, you may need to uninstall QuickBooks Desktop, rename installation files left behind, and then reinstall the program. This process is called a Clean Install or Clean Uninstall.
Step 1: Uninstall QuickBooks Desktop
- On your keyboard, press Windows+R to open the Run command.
- Type in Control Panel and click OK.
- Click Uninstall Program.
- In the list of programs, select QuickBooks and click 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
- Download the QuickBooks_Clean_Install_Tool.exe file and save it to your desktop.
- Open QuickBooks_Clean_Install_Utility.exe.
- Click I Accept on the license agreement.
- Select your version of QuickBooks Desktop and 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.
- 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)
Error: Access Denied when renaming folders
- Right-click the Windows Task Bar and select Task Manager.
- Under the Processes tab, click the Image Name column header to sort the processes alphabetically by name.
- Select QBDBMgrN.exe, QBDBMgr.exe, QBCFMonitorService.exe, Qbw32.exe and click End Process.
- Click End Process.
- Click Yes to the message, "WARNING: Terminating a process can cause undesired results including loss of data and system instability...."
