After installing 7.9, every time I would run it there would be a "SpeechInstaller" window come that would eventually ask me for source. If I click cancel enough times, Calibre actually finishes launching. Until I try to convert a book, them the SpeechInstaller windows keep coming back up, requiring cancels until it is finished converting.
Uninstalled and reinstalled calibre, same problems.
Backstepped to 7.8, and it all worked like it did this morning.
fyi.
