All,
Having a really knotty problem and I was wondering if anyone could confirm if this is a bug in 10.3 or I'm not doing it right?
I have created a script tool and an associated CHM help file. In my script tool properties I have ticked on under the general tab Store relative path names. I know this is working as my script is in a sub-folder. I have organized my folder such that my CHM file is in a sub folder called Help (not unreasonable!) but when ever I click on the Tool help button on the tool script interface it opens up a blank window and then the item description page in my internet browser.
I have tried:
- Placing the CHM file in the same folder as the tbx file
- syntax of \Help\myhelp.chm
- syntax of ..\Help\myhelp.chm
- syntax of .\myhelp.chm
- syntax of ..\SCTTool\Help\myhelp.chm
Nothing works! So is the path to the CHM file absolute and the relative path name is ignored? This is on my c:\ drive and when I double click on the CHM file it opens as expected.

OK it's ArcMap being ArcMap...
Out of pure frustration I closed ArcMap down, opened it up, went to the tool and navigated to the help file (CHM), this time it just worked...
To test it was relative I copied the entire folder structure to a new location, deleted the old one and it opened when I clicked on Tool Help.
aahaahahahaha!!!!! 
Note to self - 4 years later and I'm finding my own solutions! 
- I used .\Help\myhelp.chm
