>I have QBF Builder and have it installed for 5.0 but I can't seem to get it to install for 6.0, does anyone have any suggestions?

Can you provide more details? What version of QBF Builder are you running? It may be that you have an older version that was compiled for 5.0 only. All the latest builds of 1.x and the new 2.0 version work in VFP 5 and 6 without needing to recompile.
