3. Update Drivers or Windows Itself

Windows and driver updates are important because incompatible software could be caused by out-of-date system files and drivers. To keep Windows up-to-date, look for updates in the Windows Update settings. You should also ensure that all of your drivers, including those for your graphics card, are up-to-date.

4. Check Antivirus Settings

Sometimes, antivirus software, which is meant to protect your computer from dangers, might unintentionally block or interfere with legal apps like Microsoft Teams. To fix this, you need to check the settings of your antivirus software. You could have trouble installing or using Teams if your antivirus software considers it a danger. Now we’ll see whether the Error Code -6 problem is caused by your antivirus program by temporarily disabling it or adjusting its settings.

5. Clear MS Teams Cache

Microsoft Teams, like many other apps, uses temporary files and data stored on your computer to enhance performance and speed up certain operations; clearing this cache will restore the application’s original state. But occasionally these cached files become obsolete or faulty, and then issues like Error Code -6 pop up. Deleting these temporary files from the Teams cache will have the program regenerate them, which may fix problems caused by damaged data. Cached data may lead to software mistakes. 

  • Go to the %appdata%\Microsoft\teams folder on your hard drive:
  • Delete all the files and folders within this directory except for the following:
    \Local Storage
Clear Teams Cache
  • Relaunch Teams and check if the error persists.

6. Run it as Administrator

To run Teams as an administrator, you need to go into the system preferences and look for a way to give the program access to resources that are normally reserved for administrators. One possible solution to the Error Code -6 issue is to open Microsoft Teams as an administrator. This will allow you to overcome certain limits or conflicts. This step entails changing the executable file’s or shortcut’s attributes so that it may be executed with elevated rights. Do it this way:

  • If you have a shortcut to Teams or an executable file, right-click on it and choose “Run as administrator”. Occasionally, permission-related difficulties might cause Error Code -6, although running Teams with administrator credentials can occasionally sidestep this.

7. Repair Teams Installation

Software conflicts, system crashes, or incomplete upgrades are just a few of the many potential causes of damaged or incomplete Microsoft Teams installation files. If you’re having problems with your Teams installation, you may solve them without reinstalling the program by utilizing the Windows built-in tools to scan for and repair the application’s files and registry entries. In many cases, fixing any broken parts of the Teams installation is all that’s needed to fix Error Code -6. Complete this step by following the next actions:

  • Find the “Apps & features” option in Windows’s configuration menu. 
  • Click on “Microsoft Teams” from the list of installed programs.
  • Then choose “Modify” or “Repair” to start fixing it. 
  • To finish fixing it, just follow the on-screen directions.
