Wierd? Anyway, on Windows 7, I've downloaded a CHM file on the desktop and unblocked it by Property > Unblock.

I moved the CHM file to a folder on the desktop to organize the files, and when I opened the file, the content of the CHM reader couldn't open the pages in the CHM file. I've open the file property, but the unblocked button is gone. Well, I can simply download the file, though I find the problem interesting and I need to know how to troubleshoot it.

So, how can I unblock the said file?

Update Clarified location. I was referring to a folder in the desktop, not in network drive.

Maybe it's not on a local drive? If so, you can allow the viewer to show chm files on a network drive:

  1. Start -> Run -> Regedit
  2. Search key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x
  3. Create subkey ItssRestrictions
  4. Create DWORD MaxAllowedZone with value 2

This should fix it.

There is a table which shows the zone levels.

you can do it through powershell

  1. Start a powershell prompt
  2. write "unblock-file ", do not press enter
  3. Drag the file from explorer to the powershell prompt (to get the filename)
  4. Hit enter.

the file should now be unblocked.
