Hi,



This is my first ever post. I'm trying to create context sensitive support
for my Excel userform to a chm file I've created in HTML workshop and keep
getting the following error:



"The C:\filename.chm file is not a Windows Help File, or the file is
corrupted."



My aim is to use no code and simply to match the field in my userform to the
help file by the user pressing F1 in my addin.



The mapping looks correct between Helpmatic Pro and Excel, I've set the
(Excel) Project properties help file name as the chm file I've compiled and
left the Context ID as 0. In my userform, I've correlated the various
textboxes and combolists to Help Context ids of 20,000 or more and checked
that this mapping is correct. This returns the above error.



I've done some research on this. I can confirm that hh.exe maps to chm files
in Folder Options. There is no unblock properties in properties of the file.
I've renamed the hh.dat file in my profile to generate a new copy. The help
chm file is on my local drive. I've tried this on a colleague's machine with
the same error. I've tried opening the file through cmd line, the chm file
displays without error but as soon as I specify the context id the window
does not display.



Is there a security update that could be causing the issue? If anyone has
any ideas I would be most appreciative.
