How do I install on Windows XP? Getting an error: Entry point not found

    Cancel

    Hello Mailofkfm,

    This error can occur when the Microsoft .NET Framework Installer cannot install and/or update your system. Possible causes include:

    • Damaged Windows file and folder permissions
    • Damaged Windows Registry key permissions
    • Damaged Microsoft .NET Framework installation

    Solution

    If error 1603 occurs while updating TurboTax, your best bet is to download and install a manual update.

    If error 1603 occurs while installing TurboTax (or in other situations), it may be related to the .NET Framework. See our comprehensive article on Troubleshooting Problems with the Microsoft .NET Framework for more help.

    Note: We also suggest using Windows Update to ensure that your operating system is up to date, as this can resolve a 1603 error.

        People come to TurboTax AnswerXchange for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

        1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
        2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
        3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
        4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
        5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
