Jus tried the com registration fixing toll, and it does not
fix the proble.
I ran the NVDA installer in administrative mode to make sure
it could update registry, restarted the machine after that,
but no improvement.
the following might help. There is a next snap shot that is
meant to fix it but not sure if it is totally finished for
the snap shot was created last night and can be found at
You can jump down by headings to where the next snap shots
are and there is a download link.
But if it is the same bug i have seen you will not be able
to use your browser to get it. may be a sighted friend can
grab it for you?
I am just downloading it now and will also drop box it for
you if you can not get it that way. It can be gotten from https://www.dropbox.com/s/a4nazm0q8te5ivg/nvda_snapshot_next-14952%2Cdd1cbe50.exe?dl=0
If you do the following in the email to get it you should
get it down. Locate the second link which is the drop box
link with the letter k for link in the email. Then you will
need to use the applications key on the link then arrow down
to save link i think it is then press the enter key. It will
ask you to save it some where save it some where easy to
find like the desk top.
If you can not use nvda you might have to use narrator to
locate the link and do the same.
When the file is on the desk top or where ever you put it
locate the next snapshot file then press the enter key on
it. It should start up with the musical sound. there will be
the documentation screen tab to the check box and agree to
it. It should not have to be installed. Tab again then use
the nvda key + letter N to get into the nvda preferences
then arrow down to tools a sub menu will come off it then
locate the comms fixing tool I forget what it is called. You
will know it when you come across it. Press the enter key on
it it will then come up with a message likeit had to do some
thing to the registery i can not remember the wording tab to
the yes button then press the enter key on it.
Sorry i can not help you after that. I am thinking it
should fix the problems you might have to do a reboot but
not sure as i have not used the tool which is actually a
