Using 32-Bit vs. 64-Bit .NET Core Custom Actions

InstallShield 2024

Project: This information applies to the following project types:

•

Basic MSI

•

InstallScript MSI

When you build a release that includes a .NET Core custom action in your project, InstallShield attempts to determine the target architecture (32 bit or 64 bit) of the main .NET assembly that is associated with the custom action. InstallShield does this by examining the portable executable (PE) file for the assembly and determining if the PE file is 32 bit or 64 bit. If the PE file uses Microsoft intermediate language (MSIL) code, InstallShield treats it as 32 bit. InstallShield configures the release so that the appropriate version of the .NET Core—32 bit or 64 bit—is used to run your managed code at run time.

If you want to override the built-in default behavior, use the Direct Editor view to add a new record with the following fields to the ISClrWrap table:
