Plesk Management Service fails to start. When trying to start a service using the Services Management Console (services.msc) an error is displayed:
Error 193: 0xc1 Service fails to start
Or other service failes with the error:
Could not start the <Service Name> on the local computer Error 193: 0xc1
Unable to access Backup Manager:
Cannot create process: C:\Program Files (x86)\Parallels\Plesk\python\python.exe "C:\Program Files (x86)\Parallels\Plesk\admin\bin\PMMcli-runner.py" --get-tasks-list at (wmain line 63) at Unable to execute Python script(wmain line 86) Execute file name: C:\Program Files (x86)\Parallels\Plesk\admin\bin\PMMcli.exe
When the Microsoft Service Control Manager launches a service it checks the path to the executable. If there are any files with the same name in the directory as the the first word in the directory name, it will fail with the above error.
A file with name "program" in your System drive (C:) or drive where Plesk is installed.
Make sure that there is no file with name "program" in the root of your System drive (C:) or drive where Plesk is installed. Rename it if such file exists.
