Re: i can't play network red alert 2

thank you 

but for Serial number the answer it's not clear for me  i don't understand what  must i do

what these :I suggest making it then. Right click, New -> String value, rename it to "Serial", and then edit it and type anything you want in there, and make sure it's different on the two PCs. ???😕😃

@DragoooonSlayer Go back to that page, and read everything there. It's all explained if you just scroll beyond the "accepted answer" at the top and read everything in the right order.

I can't control what people mark as "the accepted answer". The post I linked to specifically says to read everything on the linked page, since the actual accepted reply is just a small extra note at the end. 🤨
