1. Check your antivirus

According to some users, your antivirus can cause the Error opening file for writing message to appear.

Even though your antivirus is crucial when it comes to protecting your safety online, sometimes the antivirus can interfere with your files and cause this error to appear.

To fix the problem, users are suggesting to change your antivirus settings and check if that solves the issue. You can start by disabling certain features and see if that helps.

If you don’t know which feature to disable, you can always disable your antivirus altogether and check if that solves the issue.

If that doesn’t help, you might have to remove your antivirus and check if that solves the issue. Since your old antivirus was causing this issue, it might be a good idea to switch to a new antivirus software.

There are many great security tools available, but the best are Bitdefender, BullGuard, and Panda Antivirus, so feel free to try any of them.

6. Change the security permissions

By default, regular users aren’t allowed to install applications, and if you try to do that, you’ll probably encounter this error message.

If you can’t install a certain application as a regular user, we strongly advise you to create an administrator account or try to install the application as an administrator to avoid this issue.

If you don’t want to use an administrator account, you might want to change security permissions. To do that, follow these steps:

  1. Locate the folder in which you’re trying to install the problematic application. For example, it could be C: Program FilesSteam directory.
  2. Once you’ve located the directory, right-click it and choose Properties.
  3. Navigate to the Security tab and click the Edit button.

If both of these options aren’t working for you, you might want to try changing advanced security permissions by following these steps:

  1. Locate the folder in which you’re trying to install the problematic app. In our example, we’ll use C: Program FilesSteam.
  2. Right-click the folder and choose Properties.
  3. Navigate to the Security tab and click the Advanced button.
