Failed Plesk upgrade. In C:\ParallelsInstaller\autoinstaller3.log the following error appears during upgrade using Plesk autoinstaller:

    installing Parallels Presence Builder...
    MSI: Error! Critical action 'Configuring Sitebuilder database...' failed:
    Command "D:\Parallels\Plesk\admin\bin\php.exe" -dauto_prepend_file="" "d:\Parallels\Plesk\sb\utils\configure.php" --init_db --skip_database_creation --merge_config failed with code 255.


Cause is custom PHP installation. Custom php.ini is used when running Plesk post-install scripts instead of Plesk one (%plesk_dir%\admin\php.ini).


  1. Make sure that there is no custom PHP settings in registry (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PHP or HKEY_LOCAL_MACHINE\SOFTWARE\PHP). Example of custom installation:


    If there is, it would better to uninstall custom PHP (if it is not used) or rename directory D:\PHP\ if uninstallation is not possible at the moment.

  2. Delete any custom PHP environment variables (if they exist):

    • Right-click My Computer, and then click Properties.
    • Click the Advanced tab.
    • Click Environment variables.
