I have a .chm file. On one desktop computer (Windows 7) it works fine; on another computer with the same OS, it shows the following error on the same file:

Navigation to the webpage was canceled

What you can try:
Retype the address.

How can I fix that?

Try right clicking on the file, go to properties, and see if there is there is a button to "Unblock".

If so, click it.

Additionally, if you're trying to open the file from a network share, copy it to the local computer's hard drive, and try opening it from there instead.
