While upgrading Parallels Plesk, the autoinstaller shows the following error:

ERROR: The installation of the package 'mysql' failed with code 1603. (upgrade: upgrading Parallels Panel SQL server...)


The root cause is not clear. Additional research is required to understand the real cause of the error before performing resolutions steps.


See if php.exe is broken by launching it manually. If php.exe is not working with specific behavior, you should try to repair the plesk-engine.msi package".

  1. Download the package 'plesk-engine.msi' from the repository.

  2. Extract the package files to a folder:

    msiexec /a C:\plesk-engine.msi /qb TARGETDIR=c:\plesk-engine\
  3. Copy the extracted files to the Plesk directory in "%plesk_bin%\admin", where %plesk_bin% is the path to the directory containing Plesk backend utilities (e.g., C:\Program Files (x86)\Parallels\Plesk\admin\bin).

  4. Run the upgrade again:

    "%plesk_bin%"\ai.exe --console

For more details, refer to How to restore files from the plesk.msi package.
