Error with add-ons
Justin Coffin
Hello,
When NVDA starts, I get an error message that says something about operations with add-ons failed and to check the log file for more information. Here’s what I found.
ERROR - synthDriverHandler.setSynth (10:04:07.343) - MainThread (20952):
setSynth failed for silence

Even after disabling the add-on in question, which in this case would be the IBM tts driver for NVDA, and uninstalling it, I still get the same error message. Any ideas as to what’s going on here?
Thanks.
