"Navigation to the webpage was canceled" error is displayed when trying to open and view the Microsoft Dynamics CRM 2011 Implementation Guide (IG) .chm file.

I recently ran into an issue when trying to view the Microsoft Dynamics CRM 2011 Implementation Guide (IG) .chm file.


I was getting the following error message:  “Navigation to the webpage was cancelled”

I found out that this was being blocked on my machine based on some security settings.  I had to right click and go to the Properties of the .chm file and click Unblock.  Then I was able to view the CRM 2011 IG .chm file successfully.

Hope this helps!


Here are the detailed steps to resolve this error: “Navigation to the webpage was canceled”



  • 1. Navigate to the folder you extracted the Implementation Guide files | Right Click on the .chm file | Select Properties.



  • 2. Select the ‘Unblock’ button at the bottom of the General tab and then click OK.


You should now be able to view and search the CRM 2011 Implementation Guide chm file successfully.

    @Sai- I am sorry to hear the unblock button is missing for you.  I have never seen that and even when I did some searches online I saw that a few people had run into this, but I didn't see any resolutions.  It could possibly be a permissions issue or group policy issue.  You could try open this on another computer, or one that is not on your domain to see if it's a permissions or group policy issue.

    If that doesn't work you may want to try contact Windows support to see if they have any other ideas.  

    I am sorry that I don't have more to offer on this issue.
