• Previously the content of the folder C:\ParallelsInstaller was manually cleaned up (some .msi packages were removed)

Cause

This is a Plesk bug #PPPM-7937 that will be fixed in future Plesk updates.

Resolution

1. Connect to the server via RDP
2. Launch command prompt cmd.exe from Start

3. Remove corrupted package by using MsiExec.exe and the GUID mentioned in the error message in C:\ParallelsInstaller\autoinstaller3.log log file:

   C:\> MsiExec.exe /X{AA541393-EA1C-4BA1-99D7-41CDE40110BF} AUTOINSTALLER=1

4. Re-run update.
