To have the component registered as 64 bit, select Yes. To have the component registered as 32 bit, select No.

If the component is 64 bit and it is replacing a 32-bit component, be sure to give the component a new GUID in the Component Code field.

InstallShield supports 64-bit self-registration of COM servers. If you mark a component as 64 bit and then add a file to that component, you can select the file's Self Register check box to enable 64-bit self-registration of that file during installation. The Self Register check box is on the file's Properties dialog box.

InstallShield also supports 64-bit self-registration of dynamically linked COM servers. To enable this, select the Self-Register all files check box on the Dynamic File Link Settings dialog box when you add the files dynamically to a 64-bit component.

For more information about 64-bit support, see "Targeting 64-Bit Operating Systems" in the InstallShield Help Library.

Note that 64-bit support requires Windows Installer 2.0 or later.
