    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 V4.1 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.
