Inno-setup 32 bits et 64 bits en un

Question

Est-il possible d'ajouter un fichier disant "x64.dll" lorsqu'il s'agit d'une installation 64 bits et "x86.dll" lorsqu'il s'agit d'une installation 32 bits?

Answer 1

C'est possible. Jetez un œil à l'exemple 64BitTwoArch.iss (en particulier le booléen 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).
