NSIS bootstrapper with conditional prerequisites

[adrian0b]

Hi,

I want to create an installer that bundles some driver installation files together with my application.
Basically I do something like this:

var setup = new NsisBootstrapper()
{
  Prerequisite =
  {
    FileName = @".\\res\CP210xWindows\USBXpressInstaller_x86.exe"
  },
  PrimaryFile = productMsi,
  OutputFile = $"whatever.exe"
};

My challenge now is that i need to provide an x86 and an x64 version of the driver installer.
I could simple build two installers, one for each but I am trying to figure out a way to bundle both driver installers and install one of them accoring to the target machines system.

Is there a way to do that?

Thank you,

Adriano

Hi Adriano,
Pack driver installers as two separate payloads, as in this example here payloads and write a tiny app (that's going to your prerequisite) that will run one of them based on the architecture.

Hope this helps,

Hi Tigran,

thank you for your input. I will certainly try that.

How can I access the prerequesite Payloads from my prerequesite app? It seems this isn't shown in the example.
Is it just placed in the same folder?

Thanks,
Adriano

I don't have a dev setup ready to confirm, but I am fairly certain it will be in the same folder as the prerequisite executable, extracted to a temporary folder within the windows main temp directory.
