  PLESK_ERROR: Can not retrieve information about memory usage:
  Completed only 0 of 4 bytes at (Con::OverlappedPipe::internalComplete line 392) at Unable to call readMessage() (RunTume::PipeClient::readMessage line 122) at execUtil("C:\Program Files (x86)\Plesk\admin\bin64\repairmng.exe" --get-system-resources) (PleskRepair::DefaultSystemHelper::execUtil line 45) at Repair action 'repairmng.exe --get-system-resources' execution failed(PleskRepair::ExecUtilAction::execute line 33)

Cause

Corrupted repairmng.exe file.

Resolution

1. Connect to the server via RDP.

2. For security reasons copy the current C:\Program Files (x86)\Plesk\admin\bin64\repairmng.exe file to any directory, for example, to the Desktop.

3. Create a temporary directory on a Desktop named 'Backend'. Its full path will be: C:\Users\Administrator\Desktop\Backend.

4. Start the Command prompt.

5. Switch to the directory where Plesk MSIs are stored. It's located in C:\ProgramData\Plesk\Installer\... or in C:\ParallelsInstaller\....
   Select the latest version of Plesk available in the directory. The command should be like below:

   C:\> cd C:\ProgramData\Plesk\Installer\cache\pool\release\PANEL-WIN_18.0.XX\dist-windows

6. Unpack the plesk-backend.msi from this directory to the temporary folder created on step 3:

   C:\> msiexec /a plesk-backend.msi /qb TARGETDIR=C:\Users\Administrator\Desktop\Backend

7. Replace the original C:\Program Files (x86)\Plesk\admin\bin64\repairmng.exe file with the one from the unpacked MSI C:\Users\Administrator\Desktop\Backend\Program Files\Parallels\Plesk\admin\bin64\repairmng.exe:

   C:\> copy "C:\Users\Administrator\Desktop\Backend\Program Files\Parallels\Plesk\admin\bin64\repairmng.exe" "C:\Program Files (x86)\Plesk\admin\bin64\repairmng.exe"
