Today (i know is almost time of breakfast) i download f2 german and f1 in spanish from offline option . Now i check and try open and i can't open installer (no screens no error just can't open) Propably problem is there is no data of fr Fallout 2 and Fallout 1 .Someone have same problem?

If you downloaded the "offline backup installer" then it won't be downloaded to Gog or Game-folder but to the folder you set as general downloadfolder.
Additionally the download won't be necessary the installer itself, it might be a zip/rar/...file that might be named after the
latest version.

If there's still nothing to be found same kind of critical failure occured ;)

If i try by downloader as some time ago i have an information about an error : unknown protocol. if i try by offline option i hae another problem : a click on the icon of loading the game but nothing happen. I'm a little cofused because in another game hoi2 i there is no problem with that. Propably someone add posibility of chance a language in a moment i try another time.

Heh propably the problem is that , in another computer i don't have internet connection .
