Opening the OCS Help File gives HTML blocked content error

I’ve been doing a bunch of work recently with OCS in various lab scenarios and am really pleased that the OCS product group have bundled all their documentation into a CHM file like the Exchange team have done for a while.

The only weird thing about using the downloaded help file (see link below) 

is that on opening it, it doesn’t show content instead giving an error message as shown below:


So what it turns out, is that this only happens when you download the CHM file directly because when doing that, you are prompted about the possible security threat from opening it.

To get around this, I uncheck the box to always prompt on opening this type of file;


at which point, the CHM file works correctly.


Hope that helps someone.
