Q:

chm viewer unable to show contents

I have a chm file that I can open at home. I use windows XP at home and at work. However, when I open the file at work it doesn't show the contents of the file. It properly shows the TOC for the file though. Any ideas pls?

A:

Try to right-click on your chm file and select properties. You will see an "Unblock" button. Click on it, it should solve your problem.

A:

Other than what Nicolas suggested, you may not be able to see contents of a CHM that you open over a UNC path. If that is the case copy the file to a local drive.

A:

just go to power shell and run it as administrator, 
cd your folder
and use the following command
Unblock-File '.\filename.chm'
