Thank you for your post.
I have successfully created MSI files using the Configurator with the Host installed in the past. I tried today and it failed with a warning dialog that states "Remote Utilities Host was found on this computer. It must be uninstalled.
Please, check if there is a registry entry
. If so, feel free to delete this key restart the Viewer and try configuring again.
By the way, we recommend that you use the Online configurator option over the Legacy option. With the Online configurator option your Host installer will come signed with our digital signature. Besides, this ensures that the input Host file (the vanilla Host fed to the configurator) is the correct file.
