"Internal Eror 2902, ixfAssemblyCopy" when trying to install Xcelsius Present 2008 Fix Pack 3. Any ideas as to why this might be throwing an error? I was able to successfullly install the "Xcelsius 2008 Service Pack 1 - Fix Pack 3" a couple of weekes ago but this one consistantly fails. For that matter what is the difference between the "Present 2008 Fix Pack 3" and the "Service Pack 1 - Fix Pack 3"?
