Is there a way to use Applescript to tell the finder to launch an app in 32 bit mode or 64 bit mode?  Or maybe set an attribute of the app to indicate this and then launch it?

What I really want is a way to make an alias to an app to launch in a particular mode and then just double click that to launch the app without having to worry about the path to the app in an Applescript, but that doesn't seem possible.

The Oct 2009 issue of MacTech magazine had an interesting article ...

Unfortunately, this link only allows you to read the first paragraph.

The info you need begins on page 64, under the heading "64-bit" which continues to the next page with ...

"Ideally, your application should run as 32-bit on 10.5 and 64-bit on 10.6."

and continues with an explanation about what to put into an application's Info.plist file to make it do just that. Like this ...

Luther, have you tried this? Have you got it working? No matter what I change in the Info.plist it doesn't make any difference as to whether the .app launches in 32 or 64 bit mode.

When you click the "Open in 32-but mode" in the "Get Info" window, it doesn't update the app's plist, it makes an entry in the launch services database.
