Thanks for the quick reply, Shaker. I went to the start menu under Eagle Dynamics/DCS World but the repair and update options are not listed. I am at a loss now. Here is what I have done so far: I managed to dowload LOMAC and FC1 and both work fine. I then tried to download FC2 but some reason the 1-bin file was not recognized when I clickex on the .exe file. The error message kept telling me that 1-bin was missing and insert cd 1 eventhough the bin file was clearly visible.*I then installed DCS World, CA, and A-10c with non problem. Next I attempted to install FC3. I got an error message stating that FC3 could not be installed on an older version of DCS World and that I could fix the problem by clicking on the DCS World repair functi. Now, I am unable to find the repair function. My knowledge of computers is slim to none. Any help would be greatly appreciated.
