>You could make backups of the VFP6 executable and run time files by renaming them or moving them into another directory and then running them from the other directory. Make sure that the run times are in the directory of your backup instead of the SYSTEM directory where they are usually kept.

Thanks for the info. I figured it would not be possible without doing some manipulation of the runtimes.

>Why are you wanting to have both copies around?

I have one VFP 6.0 app with a large install base. The clients are NT power users and I do not want to expend the time to re-install for an update. We have a launcher that performs application updates as required. Since the launcher itself is in VFP it cannot update the runtime's. To install the SP3 runtimes we would have to physically go to each user's machine. Major drag since we just spent three weeks installing the app about a month ago.

So now I have two flavors of VFP 6.0 apps to support. It would be nice to be able to do development for both on one machine.
