"Our course work involved learning how to fix computer parts"

Is the word "how" in that sentence really necessary?

It's not strictly necessary, but I like it.

Then how come this sentence is considered wrong:
"He has learnt to install this electric equipment."

I was told there must be a "how" preceding "to install" or else the sentence has no meaning.

You were misinformed.
