Corrupted Python installation.


Reinstall Python using the following steps:

  1. Launch 'python.msi' insaller from C:\\ParallelsInstaller\\parallels\\PANEL-WIN_<plesk_version>\ hirdparty-msi-Windows-any-x86_64 folder

    Note: For Plesk 12.5 upgraded from previous version, python.msi should be taken from C:\\ParallelsInstaller\\parallels\\PANEL-WIN_12.0.18\ hirdparty-msi-Windows-any-x86_64

  2. Follow the installation wizard instructions, specify C:\\Program Files (x86)\\Parallels\\Plesk\\Additional\\Python\\ as installation path

  3. If the issue persists, launch 'plesk-python.msi' from C:\\ParallelsInstaller\\parallels\\PANEL-WIN_<plesk_version>\\dist-msi-Microsoft-2003-i386 folder & reinstall Plesk Python.
