Package Type missing

[NickBrown]

Hi,
I want to create a package that will install on both 32 bit and 64 bit Windows.
According to the help system I can select one of these four options for the 'Package Type':-
32-bit package
64-bit package for x64 processors (AMD64, EM64T)
64-bit package for Intel64 (Itanium) processor
Mixed 32/64-bit matching the platform

My version, which is 6.7.1 running on Vista Business (32 bit) has only the first three options in the drop down list.
I guess I've missed something pretty obvious!

Any help would be much appreciated.
Thanks, Nick

Hi Nick,

Please note that a mixed 32/64-bit package can be created only by using an Enterprise project. You can change the project type by using the Project -> Options menu.
