Cannot open chm files

[mnicks]

I cannot double-click and open a chm help file. I've seen fixes for opening
them in ie and in vista, but nothing about how to fix them so they can be
opened directly in xp.

Sorry I mis-stated the problem. The file actually does open. The TOC is
shown in the left frame. However, the contents do not display in the right
frame. Instead I get an error that the address is not valid. I've seen MS
reports that it's related to a security patch that blocks the display. I've
seen KB solutions regarding Internet Explorer changes - none of which seem to
apply to opening it directly on a local drive. And I've seen resolutions for
Vista relating to Unblocking - which is not an option in XP. Nothing seems
to resolve the problem. I have noticed that if the help file is invoked from
an application by pressing F1 (or clicking on the Help menu) it display
properly.

What version of XP? (SP1,SP2,SP3)
Did you actually try any of the KB solutions?

I see some have had success with the method in Example 2 of the above,
e.g. http://www.west-wind.com/wwthreads/Message1M70OCNYU.wwt

Shows a toc but no data, just an error for data?

Check the files Properties: If it's blocked, unblock it.

That's always been my fix at least.

The regedit option worked. Thanks!
