Unlike some I was able to load and run C&C 3 without problems and get straight into the game. I have only tried a campaign so far so do not know if the problems are also present in skirmish mode. It wasn't until I couldn't destroy Kanes Prime Building during level 8, I think it is, that I wondered what I had missed earlier. After replaying the whole section again, several times, I realised that among other things I wasn't ever getting control of the ion cannon, yes I had built the support building. I went back to the very beginning and in the first level the requirement to build a base defence tower was not possible as it did not appear in the construction yard options. Carrying on it seems that certain buildings or improvements just don't appear as options. Has anyone else found this and if so fixed it. I would like to try my hand against the alien hordes in the campaign level but can't get past the huge NOD base as the final building is indestructable.
