If your Excel sheets use VBA to get values via OPC, then you'd just have to alter the VBA to connect to your RSLinx Gateway Server and set your DCOM configuration. I could establish a connection with RSLinx Classic, but I couldn’t actually get any of the tags to show data. I'm thinking that your Excel sheets probably use DDE which only works within the local operating system, which is why your previous installations of RSLinx worked fine. Does your Excel sheet contain actual OPC-related VBA code? Or is it using DDE and you see something like this in the cells?:
See here: and DDE are two different things also. You should be able to get online with PLCs using Lite via a Gateway, but DDE or OPC won't working without a real license. RSLinx Enterprise v5.00.00 (CPR 9) has been tested with, and is compatible with, Rockwell Automation's CPR 9 release of the following products: FactoryTalk Services Platform (v2.10.00) RSView32 (v7.40. RSLinx Classic ite does not support DDE or OPC, and connecting through an RSLinx Gateway Server has no effect on this limitation. RSLinx Enterprise v5.00.00 (CPR 9) is a component of Rockwell Automation's latest Coordinated Product Release (CPR 9). I think there's just a bit of confusion about RSLinx versions and what they can do.

If that fails, you might have to restart.
If it does not open RSLinx might still be configured to Always Run As a Service, repeat step 2. This allows you to open the RSLinx Classic app and change settings.
RSLINX CLASSIC INHIBIT CONNECTION DRIVER
The only driver currently configured in RSLinx is the default driver the Linx Gateways, Ethernet driver. Open the RSLinx Launch Control Panel from the start menu. Start up RSLinx and the following screen or one similar should appear.
