Unable To Open Quicken For Windows After Installation

Quicken for Windows may not start because a .NET file is missing from their computers. The program requires Microsoft .NET Framework version 2.0.  Typically, .NET 2.0 is installed on Windows XP or newer operating systems.

Quicken will prompt you to install .NET 2.0 when it is not present on your computer. However, if you need to install .NET 2.0, please use the FAQ links below.

The .NET Framework is an integral part of the Windows operating systems today, and we rely on the stability of integral system components.  If after installing the .Net 2.0 framework, Quicken still does not open for you,  the .Net Framework installation may need to be repaired.  To repair your .Net installation, follow these steps:  

1. Go to the Microsoft webpage below and scroll down to the "Fix it for me" section. Follow the directions to run the Fix it wizard.
