Cause

Antivirus software is blocking access to Plesk files/services during an update/upgrade or component installation.

Resolution

1. Connect to the Plesk server via RDP

2. Uninstall the antivirus software or exclude the %plesk_dir% from the antivirus checks.

3. Reboot the server.

4. Rerun Plesk update/upgrade from Plesk > Tools and Settings > Updates and Upgrades or via a command-line interface:

   C:\> plesk installer --select-release-current --reinstall-patch --upgrade-installed-components
