>Reason I wanted to avoid the installation wizard is that real data is on users PC. What I was hoping to do was re-compile the application in VFP 6 so that additional graphic types would be available to the user. I was hoping that all I needed to do was make a copy their current folder structure and put new executable and run time files on the PC. I DO NOT want to mess up existing tables. What is the best way to do this?

I know that in InstallShield Express, I can specify which files are overwriteen and when, so I would say all files are overwritten, but not the data files.

I would also use SDT to handle structure updates and other things seamlessly in your installations.
