Tackling Non-Attached File Program Issue (Win 10/11)

The error “this file does not have an app associated with it” mainly occurs when Windows can’t find a compatible app for opening a specific file type. If you have the relevant app installed, it might not be set as default to open files of that format, or the app or file itself could be corrupted or damaged.

The error can also occur when opening folders, mainly from Windows Search, and even when running apps and games. Here are some solutions you can apply to resolve this error regardless of where you get it.

1. Ensure You Have an App Installed That Can Open Such Files

Windows presents this error primarily when it fails to find the appropriate app to open files. Therefore, first, you should check whether you have the right app installed to open files in this particular format. There are several ways to check this, but here is one of the easiest:

1. Navigate to the file that is displaying this error when you open it.
2. Right-click the file and selectProperties .
3. Navigate to theGeneral tab and look for the file format next toType of file .
   

If it’s a commonly used file format, such as PDF, JPEG, PNG, Docx, etc., for which you have the appropriate app installed, move on directly to heading #2. However, if you see an unusual file format here—something you haven’t seen before, make sure you have the appropriate app installed.

To confirm this, right-click the file and navigate toOpen with > Choose another app .

If you have a relevant app installed, Windows will suggest you select it to open the file. If you don’t see any app suggestions here, you probably don’t have any apps installed capable of opening this file type.

If that’s the case, simply go to any of your browsers, search for Windows apps that can run files in that format, and download them. After downloading the appropriate app, make it the default for opening this file type.

2. Set the Default Application for the File Type

The error message states that if the app is already installed, you need to create an association in the Default Programs. If you already had the compatible app installed or have just downloaded it, your next step should be to set it as default for files having that file type or format. Setting the compatible application as default may solve this problem right away.

If you haven’t changed a default app before, check out our article onWindows 11 default apps . The article discusses various ways to change the default app, but we recommend using the second method, which is using the Settings app. That’s because this method lets you search for specific file formats and choose a default app for them.

3. Is the Default App Already Selected? Repair or Change It

If the app you intend to set as default for a particular file format is already selected as a default application, but Windows still displays this error, the app has likely become corrupt, thus causing the error.

To rule out this possibility, you should run the App troubleshooter, update the problematic app, reset its cache, or repair and reset it. You can find instructions for performing these steps in ourg uide forfixing apps that don’t work on Windows .

Try these steps to see if they fix the problem. If the issue persists after that, we recommend you reinstall the app or select a different one as the default. If you don’t have a different app installed on your device that supports these files, install one that does.

4. Check for Specific File Issues

If you’re opening the file in a compatible app, it’s working normally, and you’ve already set it as default, but you’re still encountering the error, verify the file itself isn’t corrupt. To confirm that, open any other file having the same file format and see if it returns the same error.

If other files open without error, but the issue persists with one file, it’s likely that the file is corrupt. If that’s the case, follow ourguide on using Windows built-in tools to fix corrupt Windows files . If that doesn’t fix the problem, try using one of thededicated tools for repairing corrupted files .

Misconfiguring the Registry settings can result in undesirable outcomes and even render your device unbootable. Before you try the next fix, create abackup of the Windows Registry so you can restore it if something goes wrong.

5. Use the Registry

If none of the above fixes have been successful, try this registry tweak as a last resort:

1. Type**”regedit”** in Windows Search and open theRegistry Editor .
   
2. Paste the path below into the address bar of Registry Editor.
   Computer\HKEY_CLASSES_ROOT\lnkfile
3. Select theInkfile key. Then, look in the right pane and see if there is a string value called**”IsShortcut** .“
   
4. If it’s not there, right-click in the blank area and go toNew > String Value . Then rename it to**”IsShortcut** .“
   
5. If the string value is already there, right-click on it and selectDelete .
   
6. After that, follow step four to recreate it. Don’t forget to rename it appropriately so you don’t encounter any issues.

7. Restart your device once after that.
