>Whenever I have installed a Visual FoxPro Service Pack, I have created a new setup routine using the Setup Wizard to install the matching DLL's on the client workstations. I have a lot of client applications still using the SP4 version DLL's... can I install SP5 on my development PC and safely run the resulting EXE's on workstations with the SP4 DLL's ? Or am I asking for trouble by not upgrading their DLL's?

Joel,

I wouldn't do that. You can get unpredictable results and strange errors by running EXE with unmatching VFP runtime files.
