The CHM document suddenly cannot be opened.

 

It seems that the software for system optimization is still useless. If you want to clean up some junk files, you will delete some files that are not commonly used but are very important. If you do not clean them up, you won't be able to clean up anything.

I used a software yesterday to mess up my registry. The CHM file cannot be opened after it is not finished ......

 

CHM indicates Compiled HTML. A file icon with the CHM extension is usually a document icon with a question mark, indicating a help document. It is a file in the help document format provided by Microsoft since Windows 98, used to replace the HLP (HELP) file in Windows 95. Since Windows 98, Microsoft has built-in interpreters (tools for opening the CHM File) in the operating system, that is, HH. EXE under the Windows installation directory. The CHM file can be generated by providing HTML Help Workshop for free on the official website. Its source file is an HTML file. Nowadays, many e-books on the Internet are produced in chm format.

Register hhctrl. ocx again. Try regsvr32 hhctrl. ocx.

HH. EXE uses MS-its and other protocols. These protocols should be provided by an itss. dll and re-register the DLL: regsvr32 itss. dll.

Specific Method:

• Start running. Enter regsvr32 c: \ windows \ system32 \ hhctrl. ocx, OK, and re-associate the file;
• Execute hh.exe in the external Windows directory.
