Deploying 64-bit Applications

Both ClickOnce and Windows Installer deployment support the installation of applications on 64-bit platforms. The target platforms are x86 for 32-bit platforms, x64 for machines supporting the AMD64 and EM64T instruction sets, and Itanium for the 64-bit Itanium processor.

For procedures describing how to set up your deployment, see the following topics:

The following table lists the standard redistributables that you can use as prerequisites for your application's installation.

If you select one of the following standard prerequisites, Setup.exe will not be created because the selected packages are not available for the 64-bit platform.

If you select only custom packages, Setup.exe will be built with all the custom redistributable packages.

If you select any of the following prerequisites along with any custom package, a warning will be put in the task list stating that the selected packages are not available for the 64-bit platform, but Setup.exe will be built containing both redistributable packages.
