    DirectX修复工具(DirectX Repair)是一款系统级工具软件，简便易用。本程序为绿色版，无需安装，可直接运行。

    本程序的主要功能是检测当前系统的DirectX状态，如果发现异常则进行修复。程序主要针对0xc000007b问题设计，可以完美修复该问题。本程序中包含了最新版的DirectX redist(Jun2010)，并且全部DX文件都有Microsoft的数字签名，安全放心。

    本程序为了应对一般电脑用户的使用，采用了易用的一键式设计，只要点击主界面上的“检测并修复”按钮，程序就会自动完成校验、检测、下载、修复以及注册的全部功能，无需用户的介入，大大降低了使用难度。在常规修复过程中，程序还会自动检测DirectX加速状态，在异常时给予用户相应提示。

    本程序适用于多个操作系统，如Windows XP（需先安装.NET 2.0，详情请参阅“致Windows XP用户.txt”文件）、Windows Vista、Windows 7、Windows 8、Windows 8.1、Windows 8.1 Update、Windows 10，同时兼容32位操作系统和64位操作系统。本程序会根据系统的不同，自动调整任务模式，无需用户进行设置。

    本程序的V4.0版分为标准版、增强版以及在线修复版。所有版本都支持修复DirectX的功能，而增强版则额外支持修复c++的功能。在线修复版功能与标准版相同，但其所需的数据包需要在修复时自动下载。各个版本之间，主程序完全相同，只是其配套使用的数据包不同。因此，标准版和在线修复版可以通过补全扩展包的形式成为增强版。本程序自V3.5版起，自带扩展功能。只要在主界面的“工具”菜单下打开“选项”对话框，找到“扩展”标签，点击其中的“开始扩展”按钮即可。扩展过程需要Internet连接，扩展成功后新的数据包可自动生效。扩展用时根据网络速度不同而不同，最快仅需数秒，最慢需要数分钟，烦请耐心等待。如扩展失败，可点击“扩展”界面左上角小锁图标切换为加密连接，即可很大程度上避免因防火墙或其他原因导致的连接失败。

    本程序自V2.0版起采用全新的底层程序架构，使用了异步多线程编程技术，使得检测、下载、修复单独进行，互不干扰，快速如飞。新程序更改了自我校验方式，因此使用新版本的程序时不会再出现自我校验失败的错误；但并非取消自我校验，因此程序安全性与之前版本相同，并未降低。

    程序有更新系统c++功能。由于绝大多数软件运行时需要c++的支持，并且c++的异常也会导致0xc000007b错误，因此程序在检测修复的同时，也会根据需要更新系统中的c++组件。自V3.2版本开始使用了全新的c++扩展包，可以大幅提高工业软件修复成功的概率。修复c++的功能仅限于增强版，标准版及在线修复版在系统c++异常时（非丢失时）会提示用户使用增强版进行修复。除常规修复外，新版程序还支持C++强力修复功能。当常规修复无效时，可以到本程序的选项界面内开启强力修复功能，可大幅提高修复成功率。请注意，请仅在常规修复无效时再使用此功能。

    程序有两种窗口样式。正常模式即默认样式，适合绝大多数用户使用。另有一种简约模式，此时窗口将只显示最基本的内容，修复会自动进行，修复完成10秒钟后会自动退出。该窗口样式可以使修复工作变得更加简单快速，同时方便其他软件、游戏将本程序内嵌，即可进行无需人工参与的快速修复。开启简约模式的方法是：打开程序所在目录下的“Settings.ini”文件（如果没有可以自己创建），将其中的“FormStyle”一项的值改为“Simple”并保存即可。

    新版程序支持命令行运行模式。在命令行中调用本程序，可以在路径后直接添加命令进行相应的设置。常见的命令有7类，分别是设置语言的命令、设置窗口模式的命令，设置安全级别的命令、开启强力修复的命令、设置c++修复模式的命令、控制Direct加速的命令、显示版权信息的命令。具体命令名称可以通过“/help”或“/?”进行查询。

    程序有高级筛选功能，开启该功能后用户可以自主选择要修复的文件，避免了其他不必要的修复工作。同时，也支持通过文件进行辅助筛选，只要在程序目录下建立“Filter.dat”文件，其中的每一行写一个需要修复文件的序号即可。该功能仅针对高级用户使用，并且必须在正常窗口模式下才有效（简约模式时无效）。

    本程序有自动记录日志功能，可以记录每一次检测修复结果，方便在出现问题时，及时分析和查找原因，以便找到解决办法。

    程序的“选项”对话框中包含了7项高级功能。点击"常规”选项卡可以调整程序的基本运行情况，包括日志记录、安全级别控制、调试模式开启等。只有开启调试模式后才能在C++修复失败时显示详细错误信息，并提示用户进行手动修复。在“高级”选项卡中，可以控制C++的修复模式，默认为智能模式，即当程序检测到系统中C++存在问题时提示修复，否则不提示。强制检测模式下，程序将总是检查C++的情况，即使在C++已经正常或没有C++数据包时。默认不勾选模式与智能模式基本相同，只是修复C++的箭头默认处于不勾选状态，需要用户手动勾选后才会进行修复。不提示异常模式，只对标准版或在线修复版生效，即在常规检测后不再提示可能导致0xc000007b错误的C++异常。不检测模式，不再检测C++的状态，程序将只进行DirectX的检测与修复。C++强力修复功能，通过全新的代码设计，彻底改善对于顽固异常文件的处理，极大提高修复成功率。API Sets强力修复功能，参照了DirectX文件的精细修复方式，极大地改善了修复失败的情况。请仅在正常修复无效时再启用这两项强力修复功能。在“注册”选项卡中，程序可以自动注册系统文件夹下的所有dll文件。该项功能不仅能修复DirectX的问题，还可以修复系统中很多其他由于dll未注册而产生的问题，颇为实用。点击该按钮旁边的小箭头，还可以注册任意指定文件夹下的dll文件，方便用户对绿色版、硬盘版的程序组件进行注册。点击第二个按钮可以为dll文件的右键菜单添加“注册”和“卸载”项，方便对单独的dll文件进行注册。请注意，并不是所有的dll文件都可以通过这种方式注册。点击“扩展”选项卡可以将任意版本的程序扩展成增强版。点击“DirectX版本”选项卡，可以自行修改系统中DirectX的版本信息。点击“DirectX加速”选项卡可以控制系统中DirectX加速的开启与关闭。如果显卡驱动异常（包括显卡驱动未安装或显卡驱动太旧），程序会在该页面右上角进行提示。在“实验室”选项卡中，用户可以控制是否允许更新为最新的测试版程序，以及在更新后的数据包更新策略。

    新版程序集成了用户反馈程序，可以在用户允许的前提下发送检测修复结果。用户也可以在出现问题时通过反馈程序和软件作者进行交流，共同查找问题。反馈是完全自愿和匿名（如果不填写E-mail地址）的。

    本程序内置自动更新程序，用户只需在“关于”对话框中点击相应按钮，即可自动升级至最新版本。升级后会自动根据用户指定的更新策略更新C++数据包。如果因网络原因或服务器异常导致升级失败，用户也可以前往本程序官方博客手动下载最新版程序。

    本程序的通用版基于Microsoft .NET Framework 2.0开发，对于Windows 2000、Windows XP、Windows 2003的用户需要首先安装.NET Framework 2.0或更高版本方可运行本程序。有关下载和安装的详细信息请参阅“致Windows XP用户.txt”文件。对于Windows Vista、Windows 7、Windows 8、Windows 10及后续用户，可以直接运行本程序。

    DirectX Repair is a system-level assistant programme which is designed for addressing the problems in DirectX. This programme is installation free and can run directly under Windows OS. The main function of this programme is to check the possible errors under the DirectX, especially the 0xc000007b problems, and then fix them. This programme consists of the latest version of DirectX Redist (Jun2010), and all the DX files have the digital signatures from Microsoft. In this case, the security of this programme can be guaranteed.

    To be friendlier with the inexperienced users, this programme is designed to repair all the underlying issues by just clicking one button. Once the users click the button Check and Repair on the main form, the programme will finish verification, checking, downloading, repairing and registering automatically, without any further participation from the users, which reduces the difficulty of operating this software. Besides, this programme will notify the users of Direct Acceleration exceptions after the normal repairing processes.

    This programme is suitable for multiple Windows OS, such as Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 8.1 Update and Windows 10, and both 32-bit and 64-bit systems are supported. The programme can detect the version of the system and the bit of system automatically, and repair the necessary files accordingly. No manual settings are required.

    DirectX Repair V4.0 provides three different editions of programmes; for example, Standard Edition, Enhanced Edition and Online Edition. All editions can repair DirectX, while the Enhanced Edition can extra repair c++ components. The Online Edition is similar to the Standard Edition, but the files for repairing are not included in Online Edition. Consequently, Internet connection is required when it is repairing the files. The executables are exactly the same between each edition. What makes their differences is the data package that they include. In this context, the Standard and Online Edition could be extended to Enhance Edition if new data packages are added. From V3.5 on, DirectX Repair supports a new feature called Extending. The Extending page can be found from the sub-menu "Option" under the menu "Tool". The extending process requires Internet connection. The new data packages will be activated automatically after the successful extending. The time for extending varies from a few seconds to a few minutes according to the Internet speed. In some special cases, extending process might be blocked by firewalls. This can be solved by switching the downloading mode to a secured link by clicking the lock icon located in the top left corner of Extending page.

    From V2.0 on, DirectX Repair has updated the foundation of the programme with multithread programming technologies. The new design provides separated tasks for checking, downloading and repairing, which means that each task can perform individually without interfering between each other. The programme also improves the verification mechanism, so there will not be any errors during the verification process; however, this does not mean that the programme cancels the verification, so the security level remains the same as previous versions.

    The programme supports updating C++ components. Since most software requires the assistance of C++ while running and the exceptions in C++ might also lead to 0xc000007b errors, the programme will examine C++ during the checking process. From V3.2 on, DirectX Repair starts to employ new c++ packages, and it can significantly increase the rate of successful repairing, especially for the industrial software. Such C++ repairing is only available for Enhanced Edition. The Standard and Online Edition will inform the users to switch to Enhanced Edition if the programme finds that there might be possible errors from the exceptional C++ components (not from missed c++ components). Besides the normal repairing, the programme now supports C++ enhanced repairing. You can enable "C++ enhanced repairing" from the Option Dialogue if normal repairing is invalid. Please be aware that this function is experimental and should only be used when normal repairing is not successful.

    There are two types of form styles, which are normal style and simple style respectively. Normal style is the default style, and it is suitable for most users. Simple style is a simplified form, and only the most basic elements will be shown. In this style, checking and repairing will be implemented automatically, and the programme will quit in 10 seconds after completing all the processes. This design is to provide an easy operation for some labour sensitive users, and this style is easy to be integrated in other games or software to achieve the goal of human-involved free repairing. The simple style can be enabled by following steps: open the file "Settings.ini" under the programme folder (this file can be created manually if there is no such file under the folder); change the value of "FormStyle" to "Simple"; save the file and this feature is then enabled.

    The programme can be called from command line, and it can accept commands from command line. The commands can be added just after the path. There are 7 types of commands, which are language commands, form style commands, security level commands, enhanced repairing commands, C++ repairing configuration commands, Direct Acceleration configuration commands, and copyright commands respectively. The detailed commands can be acquired by adding "/help" or "/?" after the normal path.

    This programme also provides a feature called Advanced Filter. With this feature, the users can select which files are needed to be repaired, so the unnecessary repairing could be avoided. Meanwhile, the programme can also realize Advanced Filter by creating an auxiliary file called "Filter.dat" next to the executable. In this auxiliary file, the indexes of the selected files can be written individually in each line. This feature might be only suitable for the experienced users, and it is only available in the normal style.

    This programme can record the logs automatically while repairing. Each result is recorded separately with context information. This feature is quite useful especially when the repairing is failed, since the author can analyse the possible reasons from the recorded logs.

    There are seven advanced features in the Option dialog. In the General Page, users can change some basic settings that control the operation of the programme, including log record, security level, and debug mode. The programme will notify the users about the details of C++ errors that are failed to be repaired if debug mode is on. Tips will also be given so that the users may repair these errors manually. In the Advanced Page, users can decide the mode of repairing C++ components. The default value is Intelligent, in which the programme will notify the users to repair them only if errors are existed; otherwise, if there are no errors, the programme will not show any information about C++ components. In the Mandatory mode, the programme will always check and repair C++ no matter if there are errors or not. Don't Tick By Default mode is very similar to Intelligent mode, and the only difference between them is this mode will not repair C++ components by default. The users will have to tick the option manually to repair C++ components. Don't Prompt Exceptions means that the programme will not warn the users about the underlying issues existed in C++ components even if they may generate the 0xc000007b error. In the Don't Detect mode, no C++ component will be checked. The programme will only check and repair DirectX components. C++ Enhanced Repairing is a newly designed function which aims to improve the handling of some abnormal files and to increase the success rate. API Sets Enhanced Repairing references the detailed repairing scheme from DirectX files, and it promotes the results of repairing API Sets files. Please be noted that users should enable these enhanced repairing features only when normal repairing is not working. In the Registration Page, the programme will register all the dll files in your system folder automatically by clicking the corresponding button. This feature is not only suitable for the issues caused by DirectX, but also useful for the problems generated by the unregistered dll files. There is a small arrow beside this button, and it is designed to register the dll files in a specified folder. By clicking the button Add Items "Register" And "Unregister" To Dll-file Rght-click Menu, new items will appear in the right-click menu of the dll files. Please note that, not all the dll files can be registered by this method. In the Extending Tab, the programme can be extended to Enhanced Edition from Standard or Online Edition. In the DX Version Tab, the DirectX information can be amended by the users. In the DX Acceleration Tab, the DirectX accelerations can be enabled or disabled. If the graphics card driver is not valid (including not installed or too old), the program will prompt in the upper right corner of the page. In the Lab Tab, users can control the strategy of upgrading the programme.

    The new version of programme has embedded the feedback programme, and the repairing results can be sent back to the author with the permit of the end users. The end users can also communicate with the author by the feedback function to address the issues together. The feedback is voluntary and anonymous (if you do not fill in your E-mail address).

    From V4.0 on, upgrading function is embedded in the programme. The users can click the button Upgrade in the form About to upgrade to the lasted version. The C++ data packages will also be updated according to the designated strategy. If the auto-upgrading is failed due to any reasons like network or server unreachable, users can go to the official blog of this programme to download the lasted version manually.

    This programme is developed by Microsoft .NET Framework 2.0. To the users who are still using Windows 2000, Windows XP and Windows 2003, they need to install Microsoft .NET Framework 2.0 or higher versions before they could run this programme. The detailed steps for installing .NET can be found in the file "To Windows XP users.txt". The ones who use Windows Vista, Windows 7 or Windows beyond can run this programme directly on your systems.
