I am getting an error getting a USB ready for a Sync 3 update. I am trying to update to version Sync 3.4.22200 (I still get an error on the version before rhis) with navigation selected also.
Tried on two networks, same issue, so it is not that. I will try turning antivirus off though. Can you replicate it if I got you all the settings tried?
Here is the last step before it fails (when I tried this morning)
