InstallAware

I have a 32 bit installer that works fine on 32 bit and 64 bit. But, I'd like to change it so that if it's being installed on 64 bit it installs some extra files and writes some extra registry entries into the 64 bit part of the registry. However calling set system 64 etc. seems to have no effect. I have something like the below, and I get the messageBox, but I don't get the registers. I've looked at the native template, but I don't see anything in it that I haven't already tried. So, any hints?

if Variable system64 Equals AMD64
MessageBox: system64, setting 64 bit registers
Set x64 - Native 64 bit Windows, AMD64 and EM64T Architectures - installation mode
Write Registry Key HKLM\SOFTWARE\Cullimore and Ring\\SHARED_LOC, $MYLOCALAPPDATA$ (permanent)
Set Win32 - Native 32 bit Windows and Windows 32 on Windows 64 (WOW64) - installation mode
end

Dear Steve,

Write Registry command is a Windows Installer command (Purple commands)and due of this, it's execution is deferred to Apply Install command execution.

I suggest you to have a look at the following link, where more info about the Purple commands are discussed;

That said, if your code is executed within your project install script sequence and before "Apply Install" statement, it'll not work because you are restoring back the Native 32 bit mode.

If you only need to write some x64 registry Key values, you may use the code you posted, with a NATIVE ENGINE ON/OFF sequence. This will cause the immediate execution of Write Registry command.



Note! using the above approach, the created Registry Key will be not removed at uninstall (due NATIVE ENGINE the Registry Key creation is not part of the MSI database)... and it must be forcedly delete via script if required.

Hope this helps you.
