>I have a customer at has purchased the Visual FoxPro 9.0 upgrade and can not get it installed. They are receiving a message stating that a prerequisite qualifying version is not found. They currently have VFP 5.0 installed on this machine. Based on this Microsoft web page http://msdn.microsoft.com/howtobuy/upgrade/#vfox version 5.0 is a qualifying version. I have opened a case with tech support. They seem to think only versions 7 and 8 qualify. Would you have any clarification on this issue?
