Thanks anyway. Since VFP7 has replaced our beloved Setup Wizard and I have little experience with InstallShield, I have no idea what really happened during the installation. I did get a different error message this time: it's looking for mscvr70.dll and I don't see that anywhere including the dev machine where the dll runs fine, or on the microsoft site as a download. Is this supposed to be this difficult or am I lucky this week?
