Tom,

The help viewer is probably not installed on the W95 machine. If so, lay your hands on the files you need and:

copy hh.exe c:\windows
copy hhctrl.ocx c:\windows\system
copy itss.dll c:\windows\system
copy itircl.dll c:\windows\system
c:
cd c:\windows\system
regsvr32 /s hhctrl.ocx
regsvr32 /s itss.dll
regsvr32 /s itircl.dll

If you still have troubles, hit it with a big stick:

RUN /N3 hh.exe <somepath>\myhelp.chm

has never failed for me
