Here's a wizard to easily create Winapp2.ini entries.
It does everything you'll need to create entries easily (except watching the clipboard when you're in Regedit - I'll implement it later)
It requires the .NET Framework 4 Client Profile (much, much, much smaller than the full one), if you haven't got it already you can download it from here : http://www.microsoft...&displaylang=en
It should work with XP/Vista/7, however, I only tested it on a x64 Win7. I'd be grateful if someone tested it on WinXP and on a x86 build of Vista/7.
Special thanks to Ranhiru for the original idea
Here's the source - it's built in C#, and the UI uses WPF (except the open file/open folder dialogs which are in WinForms, as there's no OpenFolderDialog in WPF...). It's quite simple - I'm sure I could optimize it a bit, but the performance gain would be really small since it's already quite fast.
P.S.: I won't have any Internet access in the next ten days, so if there's any bug, I won't be there to correct it. Sorry.
