I am using WiX 3.5.1602.0. If you look at the executables with corflags, you'll see that they are compiled for the 32-bit architecture.

Probing terminated. Do we have a 64-bit compatible version of these executables? I looked at the assemblies installed when running Wix64.msi but there appears to be no difference to the assemblies themselves. What am I misunderstanding about WiX supporting 64-bit MSBuild?

The shipping wix.targets already supports 64-bit MSBuild. -- sig://boB http://joyofsetup.com/ ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
