1. If this disk is your first time to install it, it is recommended to buy another disk from another place.

2. If your friend has Red Alert installed on his computer, you can copy his program to your machine and use it directly. Or serve it on a friend’s plate.

3. I have been playing Red Alert for 7 years, and I have never encountered the situation you mentioned. However, when I go online, it prompts that the neighbor cannot be found, but it will be fine if the protocol is installed in Online Neighborhood.

Good luck.
