>Due to some special requirements of my program, i have decided to use a third party installation program to install my software.

We had an extremly long thread on that 2 weeks ago. This mention was discussed as well as other things involved in using an external tool to install Visual FoxPro. One of them was concerning to the fact that it is not legal to use another tool other than the setup wizard of Visual FoxPro to install Visual FoxPro. :) That thread was also mentioning all the required files to install, etc.
