Re: NVDA saying unknown again in browsers

Gene nz,


This is really valuable stuff! All the software is up to date so your last method looks best.


Ill run the COM Registration Fixing tool first as that looks the least complicated and may not need sighted help.


All the best,

You might need some sighted help to do the following.


This is off my website and it may depend on the version you are using of nvda.


One part is for the older nvda and one for the newer nvda do not enter those details only the lines below each one.


Do you know the nvda version?


The very last part was for the run com tool but if you have done that and rebooted and it is still playing up look for your version number of nvda.


The later one has fixed it also on later versions of windows .


hope it helps


Troubleshooting - NVDA says “unknown” or “pane” in all of your browsers, Mozilla Thunderbird email client and other places
If for some reason you have problems with NVDA saying “unknown” or “pane” check for the following symptoms:

In all of your browsers, or the Mozilla Thunderbird email client, no matter what you do, you still hear “unknown” or “pane”.

In the browser, email client and other menus you notice you cannot get into your menus, or you are unable to use the quick navigation keys

When you have been told the page is loaded and notice strange behaviour

Mozilla Thunderbird saying unknown while you try to navigate it

Your applications key does not work with it being spoken out and other strange behaviour in Windows

The running applications icons are not being spoken out
It might be a good idea to do the following:
Please note: If you are hearing “unknown” or “pane” (as discussed above) NVDA might seem like it is still working properly but it may not be completely in Windows and other programmes.
You could try the following solution which will allow you to re-register your dll files in case they are causing the problem.
Press the Windows key then type the following into the search box. Type in “command prompt”. Once you have located command prompt, in the search results, press the Applications key to bring up the context menu. Arrow down to select “run as administrator” and press the Enter key. This will take you to a command prompt window. This will not be spoken out. You may need sighted assistance for this.
Type in the following command/s:
Old NVDA, Pre 2019.3
import comtypes,ctypes;p=comtypes.typeinfo.LoadTypeLibEx(r"c:\windows\syswow64\oleacc.dll");ctypes.windll.oleaut32.RegisterTypeLib(p,ur"c:\windows\syswow64\oleacc.dll", None)
Current NVDA 2019.3 onward
import comtypes,ctypes;p=comtypes.typeinfo.LoadTypeLibEx(r"c:\windows\syswow64\oleacc.dll");ctypes.windll.oleaut32.RegisterTypeLib(p,r"c:\windows\syswow64\oleacc.dll", None)

This should re-register all components in the system32 folder.
When it is finished, you can close the command prompt window with the Alt + F4 key. You should notice now where NVDA was saying “unknown” as in some examples given, NVDA should now read the icons in the running applications area of Windows, speak the content of the webpage and menus, and also in Mozilla Thunderbird and other places in Windows including the Windows applications context menu.
Run COM Registration Fixing tool
If you are getting any of the following problems below - with Windows unregistering some of the files needed by NVDA - the following tool section in NVDA will get you out of trouble. To access this tool press the NVDA key + letter N while NVDA is running. Arrow down to the tools menu. A submenu will come up. Arrow down to the menu called Run COM Registration Fixing tool... then press the Enter key.  It should register the files needed by NVDA.

Just as in 2018 under issue #33784  NVDA says unknown instead of reading any content in Firefox and Chrome. It does work in Edge. All latest version of windows 10, Firefox, Google Chrome, Easy keys, and NVDA 2020.1.


The earlier issue seemed to relate to a windows update but I dont think there was an update in this case today.


Can anyone point to a solution? This problem began only about one week ago.
