Error 1646 installing quickbooks.msi uninstallation of the update package is not supported

SOLVEDby QuickBooksQuickBooks DesktopUpdated 1 year ago

You may see this prompt if you're installing QuickBooks Desktop Premier on a computer where QuickBooks Desktop Pro of the same year is installed, or when installing QuickBooks Accountant on a computer that already has a Premier installation of the same year.

Error 1646 installing quickbooks.msi uninstallation of the update package is not supported

You'll need to Clean install QuickBooks Desktop before installing QuickBooks Desktop Premier or Accountant to resolve this.
