When I start cedega, and press install, I get that dialogue box.

This is what I enter:



Then I click okay or whatever, and it just goes back to the main Cedega window....nothing happens.

Any advice is appreciated!

Oh, on the FIFA DVD there is:

00000000.256
AutoRun
data
fifawcpc.ico
00000001.256
AutoRun.exe
DIAG.EXE
Macromedia
00000001.TMP
AutoRunGUI.dll
DirectX
SECDRV.SYS
00000002.TMP
autorun.inf
DrvMgt.dll
Support
0compressed.zip CommonEASO
eauninstall.exe
alocale
common_filelist.txt FIFAWC06.exe

That's probably because Fifawc2006.exe is not the game installer.
Try selecting autorun.exe as the installer, or check if there is a setup.exe file inside a folder (eg: the autorun folder).

I have had generally bad times with the Cedega GUI (although the last time I used it was around 6 months ago, so it might have improved). I like invoking Cedega from the CLI, found that it just worked better.

sometimes it can take a little while for the install to actually start. might want to try waiting a bit (if you didn't already), also do as suggested and use autorun.exe instead of the exe you're currently using.

None of these solution(s) worked.

Have you consulted the cedega forums at www.transgaming.org to check running instructions for that game and compatibility issues?

you also might want to check the unofficial transgaming wiki.
