I am now able to install it! I was stupid that I didn’t install
SpeechHub exe first. This was the cause for the problem.
I have another question though. I didn’t find SpeechHub synthesizer as
fast as eSpeak or eloquence synthesizer. Anything I should do for
this?

No, I couldn't find it in the installed add-on list.

Double check in Add-Ons Manager (NVDA+N,T,A,Enter) to see whether it's

I received a message to the same effect about Speech History when I tried
to
install it two days ago (I think) and mentioned that here on the group.
Even though I got that error it appears to have been spurious, as the
Speech
History add-on is shown as installed and enabled in Add-Ons Manager.

Please report back on your findings.
