How to Fix “not recognized as an internal or external command” in Windows

Due to messed up environmental variables

One of the great things about Windows is that you canget many of your tasks done from the Command Prompton your machine. You just need to entercmd.exeand Windows will run it for you. But occasionally, you might come across errors like “is not recognized as an internal command”.

This is actually one of the most common errors you can face with the Command Prompt. As the error itself suggests, it couldn’t recognize the tool you were trying to use with the Command Prompt. There are various reasons why it happens, and also there are multiple ways to get around the “not recognized as an internal or external command” error on your Windows PC.

Why The “not recognized as an internal command” Error Occurs

Before you start applying fixes, it’s a good idea to learn why the error occurred so you can ensure it doesn’t happen again in the future.

One of the most common reasons you may get this error on your PC is because another installed app modified your system variables. This prevents the Command Prompt from recognizing commands to launch other apps or tools.

The second possible reason the “not recognized as an internal or external command” occurs is that you don’t have the appropriate program installed on your computer. It may be that the installer didn’t install the application files at the appropriate location, or the installer didn’t enable the tool to be launched with Command Prompt.

Fixing The “not recognized as an internal or external command” Error In Windows

Regardless of the cause, there are ways to fix this error and get the Command Prompt to recognize the program that you’re trying to use.

The first thing to do is verify if the program that you’re trying to use with the Command Prompt actually exists on your computer. You may have used a fake installer that told you that the program was successfully installed on your machine, but that may not be true.

There’s an easy way tocheck if the program is indeed installedon your machine.

The above isn’t a surefire way to check if a program is installed on your computer. This is because not all programs keep their files in the Windows’ System32 folder. However, it should help you locate most programs.

The “is not recognized as an internal command” error usually occurs because the computer can’t find the executable that you’re asking it to launch. However, you can provide it with the full path to your executable file and it should then be able to run it without any issues.

Specifying the full path to your executable file isn’t a bulletproof method. It can also cause the “is not recognized as an internal or external command” error if it isn’t used properly. The problem lies in the path that you specify in your Command Prompt window.

If your executable file’s full path has any spaces in it, that’s going to cause the error. This is because the utility can’t recognize the spaces, and it uses the characters up to the first space as a program name. Since that isn’t the correct path, you’ll get the aforementioned error.

You can fix this using the following method.

By now, you know that when you try to run an executable from the Command Prompt utility, it looks into the System32 folder of your Windows installation and then opens the file, if it’s available there.

What if you could place your executable file there and then access it from the Command Prompt? You can do this as long as you have admin access on your computer.

While this method works great and helps you fix the “is not recognized as an internal or external command” error on your computer, you may want to use it cautiously.

This is because each time you want to use something from the Command Prompt, you’ll need to put the appropriate executable in the System32 folder. Eventually, the folder will grow large and you’ll have a large number of files sitting in there.

It also won’t work for executable tools that require installation into a specific directory. You won’t be able to move those into the System32 folder since the installation path is defined in the Windows Registry.

We recommend you only use this solution if you can’t fix the issue using the other methods and as long as the application doesn’t require installation.

The most efficient way to fix the “is not recognized as an internal command” error is to edit your environment variable and add the appropriate file path there. This is because the Command Prompt utility looks at those paths when you enter a command, and then opens the file if it finds it in one of those directories.

By adding your file path there, you’re telling Command Prompt where a certain executable is located when you want to use it by its short-name in a CMD window.

It’s pretty easy to edit your variables and add a new path there.

The “is not recognized as an internal command” error can sometimes be very frustrating, as it won’t let you use a program that you know you’ve installed on your computer.

Using the methods above, you should be able to get rid of this error and run any program from a Command Prompt window without any issues. If any of the methods above helped you fix the issue, we’d like to know about it in the comments section below.
