Hi xalspaero

Right click a chm file and choose Open with

Does Microsoft Help HTML Executable appear in the list?

If not, scroll down and click 'More Apps'

Again check for Microsoft Help HTML Executable, if that s not in the list, at the bottom, click 'Look for another app on this PC'

Navigate to find: C:\Windows\hh.exe

If that file does not exist, click the link below to download HTML Help Workshop and Documentation, which will contain hh.exe

CHM not opening from network folder

Hello,

I can't find anything answer to my problem:

One user complained that he could not open CHM file.

Error:





He mentioned, after vacation everything worked.

What I found:

.chm not opening from network folder, after copy this file on desktop, problem solved. But the person is working with much .chm document, and copy all uncomfortable.

What I tried:

• Change HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions MaxAllowedZone to 1;2;3;4
• Create UrlAllowList in regedit.
• Uninstall last installed windows updates.
• Open from another (administrator) user on this pc.
• Change location of .chm file f:\ g:\ and other mapped disk, or open path with ip: \\192.168.1.1\folder\file.chm
• No "#" or "%" symbol in file name or path.
• No choose "unblock" in properties.
• Other computers with same windows from image, can open this file from network folder.
  

Maybe you have more ideas? Thanks.

 

can't open CHM file on win10

I have an old CHM file that won't open. I've found other people hitting this problem and one of the fixes I read about is to copy the file locally instead of accessing it from a network share. I did that but the problem persists. Can we get a patch
for this?

"Spin up a VM running windows XP" is not a good answer.
