The following settings are available for the TargetPlatform property:
The package can be installed on any 32-bit platform; when installing to a 64-bit platform, files are installed to 32-bit folders.
The package is for machines supporting the AMD64 and EM64T instruction sets; when attempting to install to a 32-bit platform or any other 64-bit platform, an error is raised and installation is halted.
The package is for the 64-bit Itanium processor; when attempting to install to a 32-bit platform or any other 64-bit platform, an error is raised and installation is halted.
When either x64 or Itanium are selected, you cannot place files in the Common Files, Program Files, or System folders; you must use the 64-bit versions of these folders instead. For more information, see.
