If you only have very few device drivers in the systems page after a new install of Project Designer, it is probably because your computer did not allow our installer to write in certain folders on the computer.
Please remember when you install Project Designer to run the installer with administrators rights, do this by right-clicking on the installer and select "Run as administrator"
If this does not help you in getting all of your devices, please find the file SetupUpdater.exe as shown in the path below and again make sure to run this as administrator as well. Accept all the pop-up boxes during the install and you should get a lot of devices to choose between!
If this does not help, try and double-click the Biamp Device Editor (Before version 1.29.0 called Neets Device Indexer) in the system tray of Windows 10, then select Download new device drivers and finally if that doesn't help, select "Reindex all devices".
