We have noticed that when downloading the TMCore EPiServer Module it is sometimes the case that the help file, .chm file does not open correctly. This article explains why, and how to fix it.

The solution

Rather than tantalize and tease with the solution, to make the chm file readable on your machine open up the properties for the CHM file and click the Unblock button.

The problem

The "problem" is caused by Windows protecting your system. Windows is aware that the CHM file originated from the internet. The help system, which is HTML based, contains code (ActiveX) which, if maliciously written, could damage your machine. Therefore, Microsoft issues are security patch (896358/890175) to disable this by default.

In order to allow the code within the CHM file to run, you must "unblock" the file.
