For security reasons, the 840135 security update prevents
unsupported use of compiled HTML Help files. After you apply 840315, only files
that have the .chm file name extension can be used as compiled HTML Help files.
Programs that use other file name extensions for compiled HTML Help files will
no longer display content by using HTML Help.
To work around this
issue, the program vendor should take the following actions:
- Update their program to support or to use compiled HTML
Help files that are named with the .chm file name extension.
- Update any existing compiled HTML Help files to have the
.chm file name extension.
