1. Please make sure that nothing is blocking the program exe. or a firewall blocking it.
2. Restart the computer just in case. (Solves more questions for almost everything lol)
3. Be sure to install the Microsoft. Microsoft Net Framework 2.0 + download if you already have this, then make sure that it is up to date. This should solve most problems with the exe.
4. Go to the game folder and try launching the "patcher_cf.exe" file manually to skip the launcher program.
5. If you are using Windows Vista, please do not forget that the following files "crossfire.exe" and "patcher_cf.exe" are all run as an administrator. (Click the right button on the file and go to "Properties" and then click "Compatibility" tab)
6. Change the "crossfire.exe" and "patcher_cf.exe" compatibility mode for Windows XP SP2 and disable scaling on high DPI settings.
You should also disable visual themes and desktop composition that does not work. (These options are located in the "Compatibility" tab in the properties files.
7. Do Dowload again and reinstall CrossFire, the CrossFire Staff is updating the Installer, from time to time for the beta version so that it can correct the problem. It is also possible that your initial download was corrupted at which point you may want to try a download manager to get the file and try again.
