Yes. Same thing happens. When I push or hold the F1 key, the game window disappears and I am back at the desktop. Then I hear the "Trainer Activated" voice. The funny part is is that there's no game running! Crytek played this one beautifully.
I overlooked a previous post suggesting to hit the F1 key almost immediately after double-clicking the Crysis 3 icon (After starting up the trainer first). This worked!! I loaded up my saved game, then hit numpad 2 for the unlimited energy. Then I enabled cloaking and the voice said "trainer activated" and the energy bar never depleted. Didn't try the other options yet, though. Thank you.
i finally managed to get the trainer to work, by getting the v1.1 fixed files (no cd fix) from a certain game****wor** site. Watch out though you have to tell your AV to not scan c:\program files (x86)\origin games folder, so that it doesn't clean the a file that's a false positive
I wonder why trainer doesn't work for some people. It's working like a charm for me.
I play hunter edition, got from origin and updated. I put the trainer in the same folder as Crysis3.exe (C:\Program Files (x86)\Origin Games\Crysis 3\Bin32). Both Crysis3.exe and trainer run in administrator mode using shortcuts created on desktop (trainer first, game, F1 and so on).
For the most part the trainer works for me if I log into Win 8 as admin and run the trainer as admin. Doesn't seem to matter if I run the game as admin or not, but I do so anyway. For the most part, all of the trainer's features work with the no-CD .exe I'm using now. I still get an occasional game shutdown or system crash, but I attribute that to the game's cheat detection trying to figure out what's going on.
A few days ago I reported that the trainer's nano upgrade feature didn't work for me. It turns out that the instruction file that I printed out (may have been the previous version of the trainer) stated that the F5 key press gives 99 nano upgrade points. The current 18.104.22.1680 version of the trainer indicates right on the menu that it is the F4 key performs that function. It WORKS!
