How often do you read the Dynamics NAV manuals (and help files) before asking for help from your collegues? If you are doing this often enough, you will know that in Dynamics NAV it is quite easy to find additional information just by clicking on the field in question and then clicking F1. Also, if you are doing this often enough, you will be the first to notice, if something goes wrong with help files. This did happen to me once – after clicking F1, I have received error (which did not tell me much):
Microsoft Dynamics NAV Classic
The Help system has been corrupted.
Ensure that the .hh files are correctly installed.
I remembered seeing similar error on good old mibuso forum (however, in that scenario, error message would be caused on purpose, by disabling the help files, so user would not be able to use F1 function). My situation was different, I wanted (and needed) to use help files and had no intention of disabling this functionality on purpose.
Google search did not really help (neither did Bing), therefore I have considered reinstalling application. However (when copying setup files), I noticed one thing – the folder for Dynamics NAV has been marked as Hidden.
So, I went to the folder properties and cleared “Hidden” property (ensuring that applied to all folders and subfolders is selected).
Then, I have started Dynamics NAV client again, clicked F1 and…
…result! Dynamics NAV client (after a little bit of thinking) has rendered the help files for me. Great!
I did go through a few more tests (trying to show/how Dynamics NAV, Program Files folders) and each time I would get same error message:
Apparently, Dynamics NAV client cannot retrieve help files from the hidden folder. I am not quite sure why, but I learnt something new today!
