Reinstall using a Clean Install

It is sometimes necessary to uninstall QuickBooks, rename installation files left behind, and then reinstall QuickBooks. This may be required when a QuickBooks function is damaged or when simply reinstalling QuickBooks does not correct an issue. This process is called a Clean Install or Clean Uninstall.

Note: Be sure to have your QuickBooks download file or your installation CD and installation license available before uninstalling QuickBooks.

   3. In the list of programs, select QuickBooks and click Uninstall.

   Manually rename the QuickBooks installation folders

   
   

   Use Windows Explorer to locate and rename each of the folder locations listed for your version of Windows.  As a suggestion, add 'old' or 'damaged' to the end of the folder name. This will prevent QuickBooks from recognizing the folder in order to create a new one.

   Windows 8, 7 or Vista

   QuickBooks 2007 and later folders:

   • C:\Program Data\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)

   
   

   Windows XP or 2000

   QuickBooks 2007 and later folders:

   • C:\Program Files\Intuit\QuickBooks (year)
   • C:\Documents and Settings\(current user)\Local Settings\Application Data\Intuit\ QuickBooks (year)
   • C:\Documents and Settings\All Users\Application Data\Intuit\QuickBooks (year)

    

   QuickBooks 2006 and earlier folders:

   • C:\Program Files\Intuit

   
   

   If you get the message Error: Access Denied when renaming folders
   
   
   1. Right-click the Windows Taskbar and select Task Manager.
   2. Click the Processes tab.
   3. Click the Image Name column heading to sort processes alphabetically by name.
   4. Select QBDBMgrN.exe, QBDBMgr.exe, QBCFMonitorService.exe, Qbw32.exe in the Image Name column.
   5. Click End Process.
   6. Click Yes to the message, "WARNING: Terminating a process can cause undesired results including loss of data and system instability...."
