we noticed that our setups that have been built with InstallShield 2012 Limited Edition always installing to Program Files (x86) even if you manually change the install destination to the regular Program Files folder.
other directory changes like "d:\wtf\..." will work properly.
InstallShield Limited Edition can create installations that install to 32-bit locations on 32-bit and 64-bit machines. However, this edition cannot create installations that install to 64-bit locations on 64-bit machines. Only the Premier and Professional editions of InstallShield include this support.
Please refer to the following help topic from the InstallShield Premier/Professional help for more information: Targeting 64-Bit Operating Systems
