Win7 64-bit CHM problem solving

Recently, a few Hujiang data, are in chm format, but in win7 64-bit, can not display the inside of the audio and video flash controls, although Opening a video file by means of a source file is cumbersome. There are not many people who seem to be on the Internet. Basically, I found several related posts. The main problem is the problem of the open program of chm, borrowing baidu chm to explain that CHM is short for English "Compiled Help Manual", that is, "compiled help file". CHM is Microsoft's new generation of help file format, using HTML as the source text, compiling and storing the help content in a database-like format.

The CHM file format is a help file system based on the HTML file feature introduced by Microsoft in 1998. It replaces the previous WinHelp help system. It is also a hypertext markup language. In Windows 98, the CHM type file is called As a "compiled HTML help file". Javascript, VBs cript, ActiveX, Java Applet, Flash, common graphics files (GIF, JPEG, PNG), audio and video files (MID, WAV, AVI), etc. supported by IEbrowser
, CHM The same support, and can be linked to the Internet through the URL. Simply put, the help file format that comes with windows
is opened by hh.exe. In the default case, %WINDOWS%/is called. Hh.exe to handle, for 64-bit windows
, there are actually 3 hh.exe, located in %WINDOWS%/hh.exe, %WINDOWS%/system32/hh.exe and %WINDOWS %/SysWOW64/hh.exe, the first two are 32-bit hh.exe (17k), only %WINDOWS%/SysWOW64/hh.exe (15k) is a 64-bit program, to be solved, need to use 64-bit hh.exe override %WINDOWS%/hh.exe to pay attention to the previous backup, and if you directly use %WINDOWS%/SysWOW64/hh.exe to overwrite %WINDOWS%/hh.exe, there should be a prompt Operation and the like, this is because the default group of this file is TrustInstaller. We usually log in to User or Administrator. To modify it, you need to right click on %WINDOWS%. /hh.exe properties, click Security --> Advanced --> Owner --> Edit, change the owner to Administrator, OK, go back to the Security tab, click Edit, check the full control, Ok, then you can cover it with 64-bit hh.exe. After overwriting, it should be normal to open chm again.
