Hi there and welcome
They stopped making updates for this a long time ago, as it was not a commercial success...
But make sure you have the latest updates on it
To do this, download the software from my link below
https://esupport.sony.com/US/p/model-home.pl?mdl=NVU74T&template_id=1&region_id=1&tab=download#/downloadTab
Onto your computer
Choose Windows XP as thats the last windows they supported.
Then run the installed program, connect the device to the computer and it will perform the latest updates.
But it is all that is available for it sorry.
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
Thank you
