Inno-setup 32bit y 64bit en uno

Question

¿Es posible agregar un archivo que diga "x64.dll" cuando se trata de una instalación de 64 bits y "x86.dll" cuando se trata de una instalación de 32 bits?

Answer 1

Es posible. Echar un vistazo a la muestra 64BitTwoArch.iss (especialmente el booleano Is64BitInstallMode):

; -- 64BitTwoArch.iss -- 
; Demonstrates how to install a program built for two different 
; architectures (x86 and x64) using a single installer.

[Setup] 
AppName=My Program 
AppVersion=1.5 
DefaultDirName={pf}\My Program 
DefaultGroupName=My Program 
UninstallDisplayIcon={app}\MyProg.exe 
Compression=lzma2 
SolidCompression=yes 
OutputDir=userdocs:Inno Setup Examples Output 
; "ArchitecturesInstallIn64BitMode=x64" requests that the install be 
; done in "64-bit mode" on x64, meaning it should use the native 
; 64-bit Program Files directory and the 64-bit view of the registry. 
; On all other architectures it will install in "32-bit mode". 
ArchitecturesInstallIn64BitMode=x64 
; Note: We don't set ProcessorsAllowed because we want this 
; installation to run on all architectures (including Itanium, 
; since it's capable of running 32-bit code too).

; Install MyProg-x64.exe if running in 64-bit mode (x64; see above),
