Downloadable .chm files not viewable (FAQ90)

In all of the .chm files I've downloaded, if I double click on the .chm, all the pages have 'address not valid', so no information is provided.

This is a known problem with downloading .chm (see but it easily solved. First download and save the .chm to a local directory. You then have two options:

a) When you subsequently double click to open the .chm file, in the Open File-Security Warning dialog box click to clear the "Always ask" check box before opening this file and then click Open (please see the attachment with Print Screen of this dialog box and check box that should be cleared).

b) Right click on the .chm file to display its properties and click "Unblock"; then you can double click the .chm file to open it successfully.
