How can I install N-Gage games from PC on N95

[erehman]

I have downloaded many N-Gage games to PC. All these games have extension "n-gage". I have transferred many of these games to "N-Gage" folder which existed on the memory card of my N95 and then run N-Gage software by clicking on its icon. It prepapres for installation but after a while error is displayed "the file is corrupted. Delete file?"
I can't understand all of my downloaded files are corrupt. But may be I am making some mistake.
I have latest v.30 software on my N95 with N-Gage plateform.
Please help!
