Hello Peter,
I'm glad to hear that you've figured out the issue and it works for you now! Yes,
rutserv.exe is a part of Viewer's installation package, which is included for updating remote Hosts and for the MSI Configurator tool as well.
On both these W7 machines, Host update using Simple Update does not work, with the same error message mentioned in my previous post.
In this case, could you please send us the latest Host installation logs for review? You can find the installation logs in the following folder:
C:\ProgramData\Remote Utilities\install.log and send them to
support@remoteutilities.com.
Looking forward to your reply.
