How to Fix the Missing "mongodb-windows-x86_64-4.4.1-signed.msi" Error on Windows 10 Uninstall

If you've run into a message saying "Missing mongodb-windows-x86_64-4.4.1-signed.msi" while trying to uninstall MongoDB on Windows 10, you're not alone. This error can be frustrating, especially since it prevents you from successfully removing the software or proceeding with a fresh installation. In this guide, we'll break down the steps you can take to manually uninstall MongoDB without the installer file.

Understanding the Problem

When you try to uninstall MongoDB, Windows looks for the specific installation file (in this case, mongodb-windows-x86_64-4.4.1-signed.msi) to properly remove the software. If this file is missing, you will encounter an error, making it impossible to complete the uninstall process. This can happen for various reasons, such as accidental deletion, failed installations, or corruption during the initial setup.

Solution: Manual Uninstallation Steps

Step 1: Delete Files from the Program Folder

The first step is to manually remove MongoDB files from the program folder. Follow these simple instructions:

Navigate to the folder where MongoDB is installed. The default path often looks something like C:\Program Files\MongoDB\Server<version>\bin.

Delete the entire MongoDB folder to remove all its contents.

Step 2: Remove Data and Log Files

After deleting the program files, you'll need to clear any remaining data and log files to ensure a clean uninstall:

Identify the data path or dbPath where MongoDB stores its data (usually found in the MongoDB configuration file, if you have one).

Go to this location and delete the folder containing your MongoDB data files (C:\data\db is the common path).

If you have a log file directory, delete those files as well.

Step 3: Delete MongoDB Services

MongoDB may also have created services on your Windows machine. You will need to stop and delete these services to complete the uninstallation:

Open the Command Prompt as an Administrator.

Use the following commands, replacing <service name> with the actual name of the MongoDB service (usually "MongoDB"):

Step 4: Final Cleanup

Once you have removed the files, folders, and services, you should also check the Windows “Programs and Features” list to see if MongoDB is still listed. If it is, you can click on it to remove any remaining entries, though it should largely be eliminated at this point.

Conclusion

While encountering the Missing "mongodb-windows-x86_64-4.4.1-signed.msi" error during a MongoDB uninstallation can be a hassle, following these steps will help you navigate through the manual removal process without needing the missing file. This method not only ensures that you completely uninstall MongoDB but also prepares your system for a fresh installation if you choose to do so in the future.
