When the CHM file is opened on the computer, the system prompts: file cannot be opened: MK: @ msitstore :( file path)

I was able to open the chm format document the other day, but I suddenly couldn't open it when I wanted to use it today. I found a solution online and hoped it would be helpful to you!

1. Check whether the language settings of your OS are consistent with that of the CHM document? If they are inconsistent, the above error cannot be opened. For example, if the CHM document downloaded is Chinese, go to the [Control Panel] to check the [custom] of the "language and region" and check whether the [region option] is China, this option has some impact on some software.

2. Enter regsvr32 itss. dll

3. Run regsvr32 hhctrl. ocx on the command line.
1. Download hhupd.exeon the Microsoft website, install hh.exe, and run it. 2. Download hhupd.exe and run it. The size of this item is 461kb 3. in c: \ windows \ system32, find "hhctrl. ocx file, and then run: "regsvr32 c: \ windows \ system32 \ hhctrl. OCX...

Solution 2:
1. Right-click to associate the "open mode" of the CHM File to \ windows \ hh.exe
2. Run regsvr32 itss. dll on the command line.
3. Run regsvr32 hhctrl. ocx on the command line.
