"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

You need to unblock the file, when you right-clik it, under "general" tab, on the bottom of the window, there is check box with "unblock" title.

Check at

slakic is quite correct.

When first downloaded, Windows systems may refuse to open a .CHM help file, showing "Navigation to the webpage was canceled!".

This is caused by a standard Windows security action; to enable viewing:

- Select the .CHM file in Windows Explorer.

- 'Right-click' to invoke the context menu.

- Select 'Properties' to invoke the Properties dialogue.

- Near the bottom of the 'General' tab will be a comment "This file came from another computer and might be blocked to help protect this computer".

- Next to the comment should be a button labelled 'Unblock'; click this button (assuming that you trust the compiled HTML help file to be benign).

- Exit from the dialogue using the 'OK' button.

... which implies that the .CHM file has NOT been downloaded (and is therefore not being blocked for security reasons); hence there must be another reason for the error message.

Can you provide more detail about the .CHM file in question (e.g. how did you load it onto your system), and exactly what the error message is.

Do you get the same error if you attempt to open any of the 'standard' .CHM files held in C:\Windows\Help and sub-folders?

... looking in more detail at your attached screen capture, it appears that the .CHM file in question may be held on a different system a1 (\\, hence your system would probably not be able to change any security settings, hence the option is not there (?)

Copy the remote .CHM file and place the copy (as a local file) on your machine, then try to open that copy.
