To resolve the issue listed in the title, install QuickBooks while preventing a check for third-party applications:

1. QuickBooks uses certain non-Intuit programs that work with your existing operating system. Perform a check for Adobe (or Macromedia) Flash Player in Add/Remove Programs before installing or reinstalling QuickBooks.
   • Click the Windows Start button and select Control Panel.
     • Microsoft Windows Vista: Select Programs and select Programs and Features.
     • Microsoft Windows XP: Double-click Add or Remove Programs.
   • Scan the list, to check if either the Adobe Flash Player 8 or 9, or the Macromedia Flash Player 8 is installed.
   • If either are displayed, skip to step 3.
     
     
2. If Adobe Flash Player 8 or 9 does not display, install Adobe Flash Player 9:
   • Refer to Adobe's Web site (http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14266&sliceId=1).
   • Click Flash Player 9 to download to the Desktop and click Save.
   • Click the Save in drop-down arrow and click Desktop.
   • Click the Create New Folder icon and name the folder Flash 9.
   • Double-click the Flash 9 folder and click Save.
   • Click Open Folder and double-click the fp9_archive.zip file.
   • Click Extract and double-click the Flash 9 folder created in step 2d.
   • Click Extract and close the WinZip window after the extraction has completed.
   • From the Desktop double-click Flash fp9_archive folder and double-click 9r124.
   • Double-click flashplayer9r124_winax.exe to install.
     
     
3. Install or reinstall QuickBooks using the quickbooks.msi installer:
   • The quickbooks.msi installer does not install any of the third-party support programs and will bypass checking for any of these programs, resulting in a successful installation of QuickBooks.Click on Install QuickBooks without checking for third-party applications.
   • If the above steps fail to resolve the issue and QuickBooks does not run after installing using the quickbooks.msi installer, refer to Non-Intuit services and programs installed with QuickBooks.
