>Built an executable, teested on my system works fine. When export to external systems get message "Cannot Locate Microsoft Visual Support Library" job cancels, what am I missing

You have to install the VFP runtime files; to do this, build an install using the Setup Wizard, and make certain to include the runtime files (check the checkbox next to it on the second screen.)

If you don't want to use a Setup Wizard install as the basis for putting the application in places, there are a number of files that must be installed properly, in many cases some of these must be registered, and there are dependencies on selected shared components on the target system. Under VFP6, the runtime file dependencies are outlined in VFP6R.DEP, and there is a sample .REG file that describes registry entries required by the operating system to locate runtime components that are not created by self-registration of the runtime libraries.
