We run a loader app always that calls our exe. The loader app verifies the runtime versions and also ocx's, etc. We have a separate runtime install that is called if the runtimes are out of date. The downloadable update includes the separate runtime app as well. You might want to include the runtimes in the downloadable update for awhile. Do you have a means of tracking the version your users are currently running? We pass a license file back and forth that notifies us of which version our users are running and which version they are licensed for.

>We are preparing to update to Service Pack 1 for VFP; however, we are concerned that our users may run into issues with the "pre-release" of our application. We allow our users to download a pre-prelease version of our application. This started in early October. We are now preparing to send out final CD versions (is there ever really a final version?) using VFP9SP1. The problem is, our users will be downloading updates from our website that were compiled in SP1 and running the EXE using the original VFP9 runtime UNTIL they get their CD and install the SP1 runtimes.
