Hello NG,

we have a 32-bit application build with VB6. This uses a 16-Bit component
(highedit.dll). As expected the app did not run under XP x64 an 2003 x64
Editions.
Now we tried it with Windows Server 2008 x64 Edition and it runs! How can
this be?

Sorry for my English

Thank you!

Oliver

Normally, 16-bit applications will not run on any x64 version of Windows, as
you're aware. I suspect, however, that in this case there is a 32-bit
version of that DLL that is being used instead, and it's transparently
substituted?
