DFX not working
 

I reinstalled it and:https://i.postimg.cc/xTpgfXfS/Untitled.png

Something seems to be corrupt... Try installing it from the official download here:

http://ftp.novalogic.com/C3/fgccgf/DFX_Install.exe

What is the key?

Use the key from your CD or any other one you have

I dont have cd nor any other key

If you don't have a key you can get one from here: https://www.gog.com/game/delta_force_xtreme

That means I have to buy?

No answers?

Yes you'll have to buy it or use a key if you already have one...

But how DFX got erased from my PC automatically? Can you give a key?

Sorry I don't have any keys and I don't know how it was deleted from your computer..

Solved.
