Link to a .chm file in MS Word using relative path

[yashr]

Hello:

I am trying to use hyperlink in MS word to open my xx.chm file. I need to go to particular location in the .chm file. This seems to work fine if I use absolute path.
ex:
mkMSITStore:C:\Temp\xx.chm::/yy1.html.
I need to set relative path so it can be distributed.
I am able to use relative path just to point to the .chm file. But, I cannot specify ::/yy1.html.
Any ideas?
Thanks.
