16-bit app runs on W2008 x64 - why?

Discussion in 'Windows 64bit' started by Oliver Schröder, May 27, 2008.

  1. 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

  2. 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?
