Problem running Mercedes epc/wis

[Dell]

Hi all
i am hoping someone can help me.
i have installed Mercedes EWA/epc/wis workshop manual / parts cat on my Windows 10,but I am having trouble running it and I have just found out that I have activated it with the wrong MAC address it is using Ethernet MAC address when it should be activated using the wifi MAC address as the Ethernet cable is not connected,but I don't know how to make the program use the wifi MAC address instead.
any help would be much appreciated thank in advance Dell

Yikes @Dell - There might be a config file or registry setting for that App however, the best idea might be to uninstall it and try again? If that fails, you might need to call Mercedes Tech Support. I'm sure it's a common enough thing they have to deal with.
