Hi,

I have some .NET 2.0 code that's been built targeting "Any CPU". On an
x64 box I need to force this to run in x86 mode under WOW64 *without*
recompiling the application . (i.e. as if the code had been compiled
targeting x86.)

Is this possible - if so, how?

(Apologies if this is not the correct group - feel free to direct me
somewhere else)

Many thanks,

Matt

Incidentally I know I could do this by launching the code from a 32-
bit process (e.g. launching from 32-bit command prompt), but if
possible I'd like to force this with something like a manifest or an
alteration to the header etc.

Regards,

Matt

Found a solution using corflags.exe in the SDK to modify the PE
header:

e.g. corflags myapp.exe /32BIT+

Which is OK if the assembly is not strong named. I would be interested
to know if the same would be possible via a manifest file.
