TurboTax Installation Problems

Error Installing
Error 1334 is a general installation error. When this error occurs, you'll receive a message that says, “ApplicationController: MSI Install Exception occurred: MS installer error 1334.” To fix this error, TurboTax must be forcefully uninstalled from your system and then reinstalled. To uninstall the program, place the CD into the drive of your computer and go to Run under the Start menu. On Windows Vista, you must go to All Programs, then Accessories, then Run. Click “Browse” in the Run window and choose “Setup.exe.” Type a space and “/u /l” (no quotes) after the last “e” in Setup.exe in the Open field of the Run window. Click “OK” or “Ctrl+Shift+Enter” in Vista to open the Repair/Uninstall Turbo Tax window. Click on the “Uninstall TurboTax” button. This will forcefully uninstall the program. Once uninstalled, open the TurboTax CD drive and reinstall the program according to the manufacturer’s directions included with the software.
Windows Installer Not Accessible
When installing TurboTax on a Windows system, you may get a “Windows Installer Not Accessible” message. If you get this message, the Windows Installer on your system is either turned off or may have corrupted files. To fix the problem, go to the Task Manager on your computer, which can be accessed by pressing “Ctrl+Alt+Delete.” Go to the Processes tab and look for “msiexec.exe.” When you find the process, click on it one time and press the “End Process” button. Close the Task Manager and go to your computer’s Control Panel under the Start menu. Go to Administrative Tools and then to Services and scroll down to the Windows Installer. Make sure that the Startup Type listed next to the installer is “Manual” and the Service Status is “Stopped.” These are the correct settings needed for a manual install. If these settings are correct, proceed with installing TurboTax as normal.
Fatal Error
Fatal error 1603 is another Windows Installer error that plagues TurboTax software installations. The error is caused by the anti-virus software, firewall or backup program on your computer. The problem can be overcome by logging into the system as an Administrator, which overrides the anti-virus or firewall features and allows you to install the software. Not having space available for TurboTax on your hard drive can also cause this type of fatal error. Deleting items on your hard drive to free up space can fix the problem.
