[Setup]: ArchitecturesInstallIn64BitMode

Valid values:

One or more of the following, separated by spaces:

Default value:


Specifies the 64-bit processor architecture(s) on which Setup should install in 64-bit install mode. If this directive is not specified or is blank, Setup will always install in 32-bit install mode.

Normally, you should not change this directive from its default value unless your application contains native 64-bit binaries.

Be sure you have read the 64-bit Installation Limitations topic before setting this directive.

If your application runs only on 64-bit processor architectures, you should set ArchitecturesAllowed to the same value as this directive to prevent Setup from running on 32-bit Windows.
