OK, so I've got my reports (a couple, anyway) upgraded to run under DFR 8.0 and that is working OK on my own machine.

So, how to get that to work at the customer?

I have specified in the Change Datasource Wizard "Choose DataFlex Managed Connection" and on the next page have specified that as "..\Data\DFConnId.ini", which works OK on my own machine (however every time I run it it defaults to a full explicit path for that DFConnID.ini file, which is obviously different on the customer's PC, so maybe... ???).

On the customer's PC (the client, not the server) I have run the "DataFlex Reports Runtime v8 32 bit" application.

Chrome is set to autodetect any proxy - there isn't one manually configured. Could it be a Windows firewall issue? If so, what?

Having a c**p day.
