I spent some time and play with LaunchBox tool (I tested Mac version, and I used PSD CC5 and OSX 10.6.8 ) and as I promised I can say a couple words about my impressions. It works as it is declared. It indeed lets to launch 32bit plug-ins under 64bit Photoshop. But not directly from "Filter" menu unfortunately. It contain a special plug-ins "AlphaPlugins 32bit Bridge" and this plug-in is presented in Photoshop 64 Filters menu. And only when I launch this "Bridge" plug-in when this plug-in replaces the Photoshop Filters menu with new Filters menu what contains a list of 32bit plug-ins. Before to use this tool it needs to setup the Bridge plug-in and set a list of folders where 32bit plug-ins are stored.
Then, it lets to work with 32bit plug-ins as with normally plug-ins from "Filter" menu. Only one plug-in can be chosen from new Filter menu and after a 32bit plug-in will be applied (or canceled) then old 64bit plug-ins Filter menu is restored.
I can conclude what this way of launching 32bit plug-ins inside of Photohsop 64 is more quick and convenient than to relaunch Photohsop in 32bit mode. But this way is little unusual and requires few additional steps.
PS. As a bonus, After I installed the LaunchBox with all this components I also can use Photoshop plug-ins under iPhoto and Lightroom. And it lets to launch also 64bit plug-ins under Lightroom because I think 64bit plug-ins as usual contain and 32bit binary part in one bundle.
Maybe, later I'll test and windows version also.
