Is not the registry, is the file exported by regedit. The /E switch tells
regedit: Export to the following file. I'm not modifying the registry (yet
;-). By now I only search some information like: What's the name of the
directory where programs should be installed? (Program Files in english),
What's the directory for the desktop? What's the directory for the menu?

Nope, didn't try.

Ok, send me it, the problem is how to run it in the right moment, I hope
I can spawn it while the file stills unaccesable.

Currently I'm trying upto 100 times waiting 100 ms between tries. In this way
if the file remains unaccesable for more than 10 second I give up and also I
don't hog the system trying so quickly.
