A registry file called WinRAR.reg which is a "clean" snapshot of the registry settings (from when the app was first ran).You'll run this file instead of the real WinRAR executable. An executable called "WinRAR_Launcher.exe".Just PM me and I'll email you the file (until I see if people are going to use these, and I set-up some permanent hosting space) My settings were preserved on each machine, and no traces were left in the registry when I was done. I've tested it on 2 XP machines and so far and it seems to work fine. The first launcher I'm "releasing" is one for WinRAR (version 3.61 specifically, but older versions should work.
This means that applications that use the registry for their settings will work from computer-to-computer (with the same settings intact), and no trace is left behind. Once the user exits the application, all those registry keys that were inserted are read-back out into a file that gets copied to the portable drive, and then the registry keys are deleted from the host machine. The way it works internally is the launcher "squirts" any registry keys the app uses into the host machine's local registry, then runs the app. I thought I'd share my progess so far though I've only tried some small apps but I'd like to move-on to bigger things like Nero and Photoshop/Illustrator. I took his original idea and expanded on it to create compiled, stand-alone launchers for some apps I had lying around, and it seems to work flawlessly. The other day I stumbled on an article by a guy named j44xm that describes how you can use batch files and Window's command-line registry editor (reg.exe) to make ALL SORTS of apps portable.
