Unable to connect to iFix: "Requested operation requires elevation" - error 0x800702e4
The error you are seeing is a Microsoft DCOM error 0x800702e4. OPC uses DCOM.
When TopView connects to the OPC server it doesn't have the ability to override a DCOM connection error. This is based on DCOM configuration for the OPC Server (run dcomcnfg).
The OPC Server is requiring elevation, and not the elevation that we offer in the Configurator.
Even though you have a user that is part of the Administrators group, this does not mean that they are elevated.
You may have success with disabling UAC according to this article, but please verify this is allowed with your IT group.
The way to change this OPC Server requirement is most likely done through dcomcnfg but we recommend going through official iFix support channels for the correct settings.
