Fix: Cannot Open File for Writing’ with VLC Media Player

The ‘Cannot Open File for Writing‘ error occurs when Windows users attempt to install or update VLC media player. In most cases, the issue occurs on machines that already have or have had VLC Media Player installed at some point.

VLC Media Player Error “Cannot open file for writing”

Most commonly, the ‘Cannot Open File for Writing‘ error is caused by multiple instances of VLC or other applications using LibVLC. To fix this, you can use Task Manager to close any conflicting VLC instance while the installation or updating sequence is taking place. However, some browsers also have the potential to interfere with the legacy way of updating the VLC Media Player application.

And under certain circumstances, some type of system file corruption can be the determining factor why your VLC Media Player installation is no longer able to update.

Method 1: Closing all VLC Instances

As it turns out, the most common cause that will cause the ‘Cannot Open File for Writing‘ error is a situation where multiple VLC instances (or any other applications that are also using LibCLC) are actively running on your machine.

If this scenario is applicable, you can fix the issue swiftly by opening Task Manager and terminating all running instances of applications using LibVLC. Several affected users have confirmed that the issue was resolved as soon as every running instance was closed.

Note: If you don’t want to use Task Manager, you can simply restart your computer and repeat the action that’s currently causing the issue as soon as the next startup is complete.

Here’s a quick guide on closing all VLC instances that might end up causing the ‘Cannot Open File for Writing‘ error:

  1. Close the setup screen where you encounter the error.
  2. Press Ctrl + Shift + Esc to open up Task Manager. Once you’re inside, select the Processes tab from the menu at the top, then scroll down through the list of processes and right-click on the process associated with VLC media player.
  3. Once you see the context menu, click on End Task.

    Note: If you confirm that no additional instances of VLC Media Player are running, look specifically for other applications that are using LibVLC.

  4. Once every relevant instance is closed, repeat the action that was previously causing the ‘Cannot Open File for Writing‘ error and see if the problem is now resolved.

In case this scenario wasn’t applicable or it didn’t resolve the issue, move down to the next potential fix below.

Method 2: Close all browser instances

One unlikely cause that might contribute to the apparition of the ‘Cannot Open File for Writing‘ error is an installation interference caused by your default browser.

As several affected users have reported, VLC’s ability to update itself can be also interrupted by an open instance of Chrome, Firefox or Brave browser.

If this scenario is applicable, you should be able to fix the issue by using Task Manager to close any active browser instance that might be causing the issue.

Here’s a quick guide on how to close any browser instance in order to resolve the ‘Cannot Open File for Writing‘ error:

  1. Close the setup that is causing the ‘Cannot Open File for Writing‘ error.
  2. Open up a Task Manager instance by pressing Ctrl + Shift + Esc. Once you’re inside Task Manager, choose the Processes tab from the ribbon menu at the top.
  3. Inside the Processes tab, scroll down through the list of active processes, right-click on your active browser instances and choose End Task from the newly appeared context menu.

  4. Once every browser process is closed, repeat the VLC update or VLC installation and see if the problem is now fixed.

In case you’re still encountering the same ‘Cannot Open File for Writing‘ error, move down to the next method below.

Method 3: Running SFC and DISM scans

As it turns out, the issue can also occur due to some kind of System File Corruption that ends up affecting your operating system’s ability to install new software. If this scenario is applicable, you should be able to fix the issue by running a couple of native utilities (DISM and SFC) that were designed to find, fix or replace corrupted instances.

Although the two utilities have similar functionality, they do things differently. For example, DISM (Deployment Image Servicing and Management) relies heavily on a subcomponent of WU to replace corrupted data with healthy equivalents.

On the other hand, SFC (System File Checker) is an entirely local tool that uses locally cached data to fetch healthy files when corrupted instances are found.

Since both utilities have their own strong suits, we recommend that you run both in quick succession in order to maximize your chance of resolving the ‘Cannot Open File for Writing‘ error:

  1. Press Windows key + R to open up a Run dialog box. Next, type ‘cmd’ inside the text box, then press Ctrl + Shift + Enter to open up an Elevated Command Prompt. If you get prompted by the User Account Control (UAC), click Yes to grant admin access.

  2. Once you manage to get inside the elevated CMD prompt, type the following command and hit Enter to initiate an SFC scan:
    sfc / scannow

    Note: It’s very important that you don’t interrupt this process once you get this started. Doing this might create bad sectors that might facilitate the apparition of similar issues in the future.

  3. After the scan is complete, restart your computer once again and wait for the next startup to complete.
  4. Once your computer boots back up, follow step 1 once again to open up another elevated CMD prompt. When you return to the elevated CMD window, type the following command below to initiate a DISM scan:
    dism /online /cleanup-image /restorehealth

    Note: To complete this scan without issues, you will need to ensure that your Internet connection is stable. This is important because DISM uses WU to download healthy copies for broken systems that need to be replaced. If you get a DISM error when you try to launch the utility, here’s how to fix it.

  5. As soon as the operation is complete, reboot your computer once again and see if the issue is resolved at the next startup.
