Problem solving under CH4 under Win7 64 bit

There have been a few Hujiang data recently, all in chm format, but under win7 64-bit, they can not display the controls such as audio and video flash inside, although the video file can be opened by source file. But it is very troublesome. 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 HTML file features introduced by Microsoft in 1998 to replace the earlier WinHelp help system. It is also a hypertext markup language in Windows
98 The CHM type file is referred to as "the compiled HTML help file". Javascript, VBs cript, ActiveX, Java Applet, Flash, common graphics files (GIF, JPEG, PNG), audio and video files (MID, WAV, AVI) supported by Internet Explorer, etc., CHM also supports and can pass URL is linked to the Internet. Simply put, the help file format that comes with Windows is opened by hh.exe. In the default case, %WINDOWS%/hh.exe is called to handle 64-bit windows. There are actually three hh.exes located at %WINDOWS%/hh.exe, %WINDOWS%/system32/hh.exe and %WINDOWS%/SysWOW64/hh.exe, the first two of which are 32-bit hh .exe (17k), only %WINDOWS%/SysWOW64/hh.exe (15k) is a 64-bit program, to solve, you need to cover the %WINDOWS%/hh.exe with 64-bit hh.exe before the coverage Under the backup, if you directly overwrite %WINDOWS%/hh.exe with %WINDOWS%/SysWOW64/hh.exe, there should be a prompt that it cannot be operated. This is because the default group of this file is TrustInstaller. , we generally log in to the User or Administrator, to modify, you need to right click on the properties of %WINDOWS% /hh.exe, Click Security-->Advanced-->Owner-->Edit, change the owner to Administrator, OK, go back to the Security tab, click Edit, put the full control on, OK, and then you can use 64 The bit hh.exe is overwritten. After overwriting, it should be normal to open chm again.
