I just bought a new PC with 64-bit Vista Home Premium. Tried installing Civ 3 (Gold). Initial installation worked fine, but when I install patch 1.29 and after executing Civ 3 the OS gives error msg that it cannot locate the CD, please insert it now and restart the program. Doing as directed makes no difference. I have only one account on the PC and it is Administrator (at least that is what it says). I installed the patch using the right click, run as Administrator as recommended above. I've installed the game under C:\Games to keep it out of the Programs folder. Still won't run. Any ideas. Thanks in advance.
