>They bought Visual Foxpro 6.0 (but not Visual Studio). We had them download Service Pack 4, but when they went to intall it, it informed them that they need Visual Studio to complete the installation. They obviously don't have the whole Visual Studio.

My guess is that they downloaded the whole VS SP4, and not just the one specific to VFP. The download should total approximately 74Mb. If it's more on the order of 129Mb, they downloaded the wrong one.
