I'm not really sure if this should be in the Bug thread or Suggestions thread, but seeing as the application is already 99% functional in Windows PE version 3.0, I'll start with the Bug forum.
Recuva (using latest version 1.31.437) launches successfully in WinPE 3.0 x86 (Windows 7 PE) but when I try and open the "Browse for Folder" dialog after selecting the files I want to recover, the dialog comes up blank. From what I understand, this could be to do with a comdlg32.dll dependancy to Internet Explorer or something along those lines. The issue being experienced is very similar to this one (from Autoit: http://www.autoitscript.com/forum/index.php?showtopic=3040).
It would be great to get this fantastic app working under WinPE, especially seeing as it allows us to recover files without the base operating system messing around with the disk. Any direction or work arounds for this would be greatly appreciated and I'm happy to help beta test etc to see if we can get this working.
