-在运行DEMO前别忘了检查自己的电脑配置！
-无论N卡还是A卡，最好检查并更新你的显卡驱动
-如果画面出现延迟，使用D3DOverrider并针对FIFA15DEMO开启三缓存和垂直同步
-如果碰到游戏崩溃，别忘了更新你的Direct X版本。（点我下载）
-如果你的手柄按键无法工作，试试这个，下载Xbox360手柄相关文件，放到FIFA 15 DEMO目录下（点我下载）
-安装Win7或者Win8支持的最新版本.NET Framework程序，避免出现相关错误。（下载地址）
-你的显卡必须支持Direct X11才能运行DEMO！
-通过禁止游戏内Origin功能来防止FIFA 15 DEMO卡死在EA LOGO出现的地方：不通过游戏启动，直接打开Origin（或者启动15 DEMO Config后关掉），在设置里找到“游戏内Origin”，把“启用游戏内Origin”取消掉。
-如果你在安装DEMO时看到下面信息“VC++ runtime redistributable package was not installed successfully. Setup cannot continue.”，打开Origin Games\FIFA 15 DEMO\__Installer\vc\vc2012Update3\redist目录，运行vcredist_x64.exe.完毕后返回Origin即可正常安装DEMO。
-如果你还出现.Net Framework错误，使用修复工具修复（点我下载）。
-如果在选择语言界面游戏崩溃，你需要重新安装Windows Media Player！这是因为游戏导引界面必须有WMP支持才能运行。（安装WMP的操作步骤请看这里，我就不翻译了，有图示：
How to Reinstall Windows Media Player in Windows 7 to Solve Problems
If you’re having problems with media playback on your Windows 7 PC using Windows Media Player, or even using other applications like Media Monkey, you might need to reinstall Windows Media Player. But how?
Reader Ted wrote in with this tip, which solved his problem of playing ripped music files in either Windows Media Player or Media Monkey.
Step 1: Uninstall Windows Media Player
Open up Control Panel and type “windows features” into the search box, and then click on Turn Windows features on or off.
Go down to Media Features –> Windows Media Player
Step 2: Reboot
That is all.
Step 3: Turn Windows Media Player Back On
Head back into Windows Features on or off, and check the box again.
At this point hopefully your problem should be solved.
-FIFA 15目前不支持特殊字符（例如àéñõü）。如果你的PC名字或者Windows用户名包涵一个特殊字符，都可能导致游戏崩溃。如果是这样，我们建议你修改PC名字和用户名字，流程如下（来自EA官方，不翻译了）：
FIFA 14 Crashes or Freezes (PC version)
Options
If you are experiencing crashes with FIFA 14 on your PC, please try the following possible workarounds as they have already been of help to other players.
If you are having trouble running the game, we recommend first making sure your Windows and drivers are up-to-date.
We are aware that FIFA 14 is currently unable to support special characters (such as àéñõü). In the case where you PC name (or your Windows username) contains at least one of these characters, it will cause FIFA 14 to crash. We suggest you to rename your PC name or your Windows user name by following the two solutions provided below:
Your PC name Contains special characters:
If your PC name contains special characters, please rename your PC name. To do so, click on the Start button and follow the below instructions:
Click on the “Control Panel” and in the “System and Security” section, select “System”.
Under “Computer Name, domain and workgroup settings” click on the “Change Settings” button.
On the “Computer name” tab, click on the “Change” button.
Then, change the computer name and reboot your computer to ensure the changes take effect.
Your Windows username contains special characters:
Please verify if your FIFA 14 config. files are located in a path similar to: C:\Users\Usernàmé\Documents\FIFA 14 (with special characters). If this is the case, please follow the instructions below carefully. As this process is a bit more complicated, if your Windows username contains special characters, you will not need to rename it but simply add a new username.
Click on the Start button.
Click on the “Control Panel” and in the “User Accounts and Family Safety” section, select “User Accounts”.
Click on “Manage User Accounts”.
Click on “Add” and enter a new user name (no special characters), and click on “Next” to finish.
Make the user an Administrator by clicking on the “Administrator” option and click on “Finish”.
(Please be aware that if you are on a network, you may need to create a local user first from the “Advanced” tab.)
Once you tried the above solution , please try to login with this new Windows user account. Once logged in, launch Origin, then launch FIFA 14 if both options are available to you. If you do not have the Origin icon on your desktop, please reinstall the clients on this new Windows session.
We thank you for your patience and we apologize for the cumbersome workarounds.
-还是无法启动游戏，试着进入我的文档，创建一个“FIFA 15 DEMO文件夹”并添加两个文件（点我下载）你可以自己通过fifasetup.ini的内容修改设置！另一个解决方法是在C盘根目录下创建相关文档，然后指定到这里。（进入原始文件夹，右键，属性，选择并指定C盘目录下的新文件夹）
-如果你的显卡性能太弱无法运行DEMO，下载运行dxcpl.exe，进入Edit List…，添加fifa15demo.exe和fifaconfig.exe，点OK，在Feature Level Limit设置11_0，点击Force WARP，最后点击应用和OK。不过这样游戏会运行得很慢！
-在训练场里使用DEMO球员玩耍的方法（注意你不能退出训练场！）：
在FIFA 15 DEMO目录下创建一个文件，命名为cl.ini ，用记事本打开，键入下列字符：
SKIP_BOOTFLOW=1
FREE_ROAM_DEMO_TEAMID = 241
FREE_ROAM_DEMO_PLAYERID = 190871
FREE_ROAM_GK_TEAMID=10
FREE_ROAM_GK_PLAYERID=150724
现在你操纵的球员是内马尔，而门将是乔哈特
这里还有其他一些球员的ID：
Lionel Messi 梅西:
FREE_ROAM_DEMO_TEAMID = 241
FREE_ROAM_DEMO_PLAYERID = 158023
Zlatan Ibrahimović 伊布:
FREE_ROAM_DEMO_TEAMID = 73
FREE_ROAM_DEMO_PLAYERID = 41236
Edin Džeko 哲科:
FREE_ROAM_DEMO_TEAMID = 10
FREE_ROAM_DEMO_PLAYERID = 180930
Mats Hummels 胡梅尔斯:
FREE_ROAM_DEMO_TEAMID = 22
FREE_ROAM_DEMO_PLAYERID = 178603
-在你的显卡控制台界面添加DEMO的项目！N卡在桌面上点击右键，进入显卡控制中心（正式中文名字忘了，我现在用的本子是A卡，下列名词同理——译者），进入管理3D设置，程序设置，添加FIFA 15 EMO.EXE。 A卡用户下载RadeonPro然后添加FIFA 15 DEMO项目。如果你的卡顿很厉害，你可以在各自的项目里直接进行调试，直至流畅！
