We have identified an issue with some of our recent device drivers on Windows 10 that started with the 1607 b14393 update of Windows 10 called the Summer Update (code named Redstone) released the last week of September 2016.
Systems that display this error have Secure Boot enabled in their BIOS and have a factory installation of Windows 10 may experience an issue where their PreSonus device driver will stop working due to a lack of a digitally signed certificate for the device driver.
This does not apply to all Windows 10 systems, however for the systems that experience this issue, we advise removing UC 1.8 or UC 1.8.1 and install UC 1.8.3 which now includes signed device drivers for all currently supported products on Windows 10 1607 b1493.
To report any issues, please contact PreSonus Technical Support by creating a Support Ticket at My.PreSonus.com/Support for further assistance.
