Can't install Orthanc on Windows 10 system

I am helping someone to get Othanc installed (OrthancInstaller-Win64-20.5.3.exe) on a Windows 10 system.
Not sure what went wrong, the installation has run. the orthanc service exist, but won’t start because the C:\Program Files\Orthanc Server folder does not exist.

When trying to run the installation again I get a message that Orhanc is already installed, but Orthanc is not in the Add/remove programs list, so I can’t uninstall.

Is there any way to force the installer to run, or is there a specific registry key that I can remove to get the installer running again?

Thanks,
Johan

Hello,

There are more recent versions of Orthanc available (the latest one being 21.1.2).

To manually remove Orthanc:

  • Open “services.msc” to stop the Orthanc service if running

  • Run “sc.exe delete Orthanc” to remove the Orthanc service

  • Open “regedit” to remove the content of “HKEY_LOCAL_MACHINE\SOFTWARE\Orthanc”

  • Remove “C:/Program Files/Orthanc Server/” or “C:/Program Files (x86)/Orthanc Server/”

  • Reboot

HTH,
Sébastien-
