c# - 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:

File AlphaVSS.WinXP.x64.dll' targeting 'AMD64' is not compatible with th project's target platform 'x86'
File AlphaVSS.Win2003.x64.dll' targeting 'AMD64' is not compatible with th project's target platform 'x86'
File AlphaVSS.Win2008.x64.dll' targeting 'AMD64' is not compatible with th project's target platform 'x86'

How can I make my setup target both platforms like my program does?

Answer 1

The MSI created by the setup project (in Visual Studio) can only target one platform at a time. Your option is to either make 2 MSI's, merge them together and make a custom setup boot strapper that choose between the two. There are some 3rd party products,like Advanced Installer for example, that can do this for you.
