Applies to: Sophos Home for Windows

You receive the following message when trying to install Sophos Home:
“Sophos Extractor
Could not extract the installation files. Please contact technical support. Error code: 30”


This error can occur due to several reasons:

  • An incomplete or corrupted download
  • A 3rd party archiving tool is installed
  • A 3rd party antivirus software is installed
  • A 3rd party file explorer (other than Windows Explorer) is installed

What to do – 4 options

Option 1 – Download a new installer file

The most common cause of Error Code 30 is an incomplete or corrupt installation file.

Please, re-download the installation file (SophosInstaller.zip) using different internet browser and re-try installing Sophos Home.

See: Installing Sophos Home on Windows computers

Option 2 – Remove or change the default archive utility (unzip tool)

Error code 30 occurs during the extraction process of the installation. The first step is that the contents of SophosInstaller.zip are being extracted (unzipped). Often, a 3rd party archive tool gets in the way and prevents the extraction.

Follow these steps to change the behavior:

1. Uninstall any 3rd party archive utilities (sometimes, updating the 3rd party archive utility might help)

2. Change the default program that handles .zip files. See https://support.microsoft.com/en-ca/help/4028161/windows-10-change-default-programs

Option 3 – Remove any 3rd party antivirus programs

As per our General FAQ, we do not recommend having additional antivirus software installed along with Sophos Home as this can and will cause conflict. any 3rd party antivirus software should be uninstalled before installing Sophos Home.

Option 4 – Remove any 3rd party file explorer programs

Disabling 3rd party file explorers (file explorers other than Windows File Explorer) during the installation process may resolve this issue.
