put your flash files IN your program with an OLE control (if you don't want the user to see them then resize them until they are small or try setting visible to false)

Set the AutoActivate property to getfocus
When you click the button have the button setfocus on the ole and that should open it.
this may work

you could also try setting enabled to false and using the command button to enable it. have the autoactivate property on manual.
i hope it works
