Best practices to create installer for app with 32-bit and 64-bit EXEs

[htome]

Hi there,

Can anyone post a link or some good practices to follow when you need to create an installer for an application that has 32-bit and 64-bit EXEs?

Should we create one installer?

What about naming the EXEs? Should it be myapp.exe and myapp64.exe? or this is completely unecessary as they should be installed under "Program Files (x86)" and/or "Program Files" and have the same name.
