RE: XP64 Manifest Achitecture problems

["Antonio Scuri" <scuri@...>]

  That's correct. The 32 bits binaries are NOT working in Windows XP x64,
although they work on Vista x64.

  But I tested on a new XP64 system without any updates because it is
offline. Maybe downloading the updates from Windows Update would fix the
problem.

  I tried also to use external manifests but they do not work. The manifest
can be changed for the current DLL, but if anyone has another solution
without changing/recompiling the DLL I'll appreciate.

Best,
scuri
