Yes, that's a much nicer file name
What about the "path".
Do you have write permissions for D:Mon DocumentosMy Music_recz
Is there enough space on that drive?
Where did you get the "1.2.6 rev 2 (portable edition)" version of Audacity from?
If it's the one that has been packaged by PortableApps you may be better asking them for support as I doubt that anyone here knows in detail what modifications they have made. Alternatively, you could try the portable version of Audacity that we can support.
The current, normal release version of Audacity 1.3 is portable. You just need to get the Zip version of it, extract the zip file wherever you want it, and create a new folder in the same folder as the .exe file and name it "Portable Settings" (without quotes). I use this all the time as most of the computers at work do not have Audacity installed.
