A couple posts above, you gave following answer:
3) C:\python27\wallet222.dat
4) wallet222.dat

I do speak a reasonable amount of French (eventough you are not allowed to post non-english posts outside the regional subforum). But what i'm seeing here is that you named your wallet wallet222.dat. So, if there is no wallet.dat @c:\python27, the command will fail...
Maybe you could try:
Just on a sidenote, this debate has been going on for days, and i sometimes feel like we're going around in circles on this one... Is there anybody you trust for 100% that's tech-savvy and is able to help you with this task? Even if you're tech-savvy yourself, it wouldn't hurt to have a second pair of eyes looking at this thread while having physical access to your system (and the wallet-file itself).
