Your welcome. I got the Corel version of Bryce in a box around here someplace also that has the help files that I think were .html files too but maybe not. I don't have it installed now and it was so long ago I forget but the Help did work on the Corel version.
Ok I found it and it is a Bryce5_Manual.pdf. dated 5/24/01 and it is a little smaller file but if you want it then get the Bryce5_Manual_Corel.pdf here.

Where on the Daz version clicking on Help does not do anything.
But that 5.0 should be what you need and I got it back on 8/23/06 alone with two Bryce.
A Bryce5FreeVersionPC.zip that you just unzip the Bryce and it is 5.0.3.0 but you have to Registration Code to get it to work. Then I got the same day  ps_ap075_Bryce5.exe but can't tell what version it is but I think it is the same.
I think I got the one download from DAZ site and the other from C-net downloads.
