Navigation to the webpage was canceled

[patrandle]

Other browsers (FireFox and Netscape) display the topics, but Internet Explorer 7.0 displays 'Navigation to the webpage was canceled' when the RoboHelp v. 6.0 chm file is launched from a subfolder in My Documents (received from another developer) for Microsoft HTML projects. The Contents and Index display, but not the associated topic. All chm files display fine when opened from the desktop AND anywhere by the author. I've researched Help and Adobe Forums, but haven't found an answer. All help indicates that only the chm file needs to be distributed. It worked fine in prior versions. Our client will probably launch the project from a network, so we need the ability to enable it from any location.

Thanks for any guidance.

Hi patrandle and welcome to our community

If you received this .CHM from another person, you will likely need to unblock it. I have instructions you may need. You may view them by clicking here.

Give that a try and let us know how you make out!

Rick, thanks for that web page showing how to unblock a CHM file. I am wondering though, is there a way to correct this problem compiling the CHM -- somewhere in the source files. I doubt it: I got nothing when I searched for "unblock" in Robo's helps.

Hi, David, and welcome,

No, I'm afraid that there's nothing you can configure in the help source files that removes the need to unblock a downloaded .chm file. If this were possible, it would undermine the security restrictions that Microsoft introduced three years ago to stop malware writers from distributing their wares via .chm files.

However, system administrators can implement a very limited set of workarounds, as described in this article in the Microsoft Knowledge Base:

Thanks so much for your help! One of my associates found the answer earlier, but I should have thanked you earlier.

Thanks!

Is there a way to correct multiple computers of this new Microsoft "feature," or will the "Unblock" need to be performed on each computer that accesses the .chm file?

Welcome to our community, Doesitall2

It all depends on how the .CHM file is deployed. If received via E-Mail or by downloading from the web, the users will likely need to unblock after saving. But if the .CHM has been installed as part of an application, they shouldn't need to unblock anything.
