>Hi all,

>I'm helping a friend install vfp 9. He has all the installation files in his C:\ drive. We run setup.exe and the first part where we install the pre-requisites has no problems, then when we run the second step to install vfp and right away we get this error "Suite Integration Toolkit Executable has encountered a problem and needs to close. We are sorry for the inconvenience.".
