A little hint for those who may not know. On this pc, since it's the company pc and I can't install things here, I run NVDA as a portable version. Therefore, if you ever want to install an NVDA addon that you downloaded from an external source such as Sonata voices or RHVoices, Windows does not automatically guess it's an NVDA addon, it asks with which program you want to open the NVDA addon...in that case, use: Install from external source within the #NVDA addon store installed addons tab. You'll then be presented with an open file/browse dialog, after which you can select wherever you put the Sonata voices or RHVoices addon, and it'll install as it should. After you've installed stuff from external sources, just tab to the close button and NVDA will come up with the normal dialog, Addons were installed/removed...you must restart NVDA for the changes to take effect...just press enter and it'll do it's thing, now you can use the addon/s you have installed.
