Setup targeting both x86 and x64?

Question

I have a program that requires both x64 and x86 dlls (it figures out which ones it needs at run time), but when trying to create a setup, it complains:

Answer 1

I ran into this too and wrote a blog post about my solution:

• deflate the file using deflate.exe, naming it with a different extension (e.g. .x64)
• add it to your main project as a content file
• add a custom action project to your solution
• add the custom action to the setup projects "Install" custom actions
• inflate the file inside the custom actions Install method using
• System.IO.Compression.DeflateStream (see code above)
• do a little dance around your desk, down the hall, and past as many coworkers as you care to annoy :)

The deflate.exe file can be downloaded from its repository on google code.
