Lost my CHM "open with" on W98SE...where do I point it?

Somehow lost the link…which module should be used to open these? I hope that link is all I am missing…if not, where do I find correct module in CABS? Thanks!

Got a mental refresher from another site…it’s “HH.exe” in Windows/System (on my PC)

Not sure why it happens…does so every few months!

is dissappears more often??

even afther a fresh install??
