To my knowledge, the msflxgrd.ocx is only supported under the 32 bit
emulation world of Windows, is not supported under the 64 bit world and will
never be supported under this 64 mode. Furthermore, even for the 32 world,
it will not be supported under the next version of Windows that will follow
Windows 7.
Your current C++ program or whatever else should work properly on Windows 7
if you target the 32 bit platform but it won't work at all if you target the
64 bit mode and there is no hope of making it works there.
