# Troubleshoot Desktop App Startup

If the Mem desktop app will not open or keeps closing, try the steps below.

<Note>
  The Mem desktop app officially supports Windows 11 and later. If you use an earlier Windows version, use [Mem on the web](https://mem.ai).
</Note>

## Example Error

On Windows, this problem can appear as an **A JavaScript error occurred in the main process** dialog that says **The specified module could not be found**.

## Try These Steps

1. Fully quit Mem, then open it again.
2. If Mem shows a **Mem could not start** message, select **Try again** once.
3. Download and install the latest version from [get.mem.ai/download](https://get.mem.ai/download).
4. Restart your computer, then try Mem again.

## Install the Windows Runtime

If Mem still will not open on Windows, or the error mentions a missing component, install Microsoft's current [Visual C++ Redistributable for x64](https://aka.ms/vc14/vc_redist.x64.exe).

You can confirm the download and learn about the runtime on Microsoft's [latest supported Visual C++ Redistributable downloads](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170) page.

Restart your computer after the installation finishes, then open Mem and select **Try again** if prompted.

## If You Still Need Help

You can keep working in [Mem on the web](https://mem.ai) while troubleshooting the desktop app.

If Mem opens but becomes stuck, follow [Reset the Desktop App](/troubleshooting/desktop-app-reset).

Contact [support@mem.ai](mailto:support@mem.ai) with your operating system version, Mem desktop version if you know it, and a screenshot or the exact text of the error.
