I got that. Exes must be different to use different runtimes. I mean one day your customer might call you and report a bug. If just exe name doesn't specify under what version you compiled it then it might be hard for you to find the correct project to check (for example our customers have multiple different applications from us. Each of the applications might be compiled with VFP5 or later. Hard to track each. Practically say my application name is myApp. It has myApp v1.0, v1.1, v2.0 ...). Not all versions are built with same VFP version. When I need to check the project and do a recompile for a bug I need to know the runtime version customer has. I can't simply go and recompile under say VFP9 even if project is fully compatible with 5 to 9 - I don't want to send runtimes again).
