Finaly it works for mee. I instald Q4 1.4.2 but i can play 1.0 to hehehe. So for the people hoe downt now that, hier is the anser to get it don.

The easiest way to run two versions of Q4 is simply to have two installations. Go to C:\Program Files\id Software\ (assuming you installed in the default location). Copy The "Quake 4" directory and then rename it to "Q4 1.0". Rename the other copy to "Q4 1.4.2". Then install the 1.4.2 patch, and when it asks where to install it, give it the "C:\Program Files\id Software\Q4 1.4.2\" directory. You can then run whichever version you want by double-clicking the right quake4.exe
Move all the files in the quake 4\ directory up a map (if you can not start it up)

You can download 1.4.2 with Xfire
if you have problems with insalling it look at this forum it helpt me a lot:
