I personally have not experienced issues with UltraChannel and iLok. My issues have occurred with VSTi plugins and stand-alones from other vendors that use the iLok software, and the iLok License Manager software itself. The error message refers to a missing component. Restarting the PACE service via the Control Panel appears to work quicker and better than a complete uninstall-reinstall of the iLok software. I have been installing a lot of plugins, virtual instruments, DAW upgrades and adds-on, sound and sample libraries (Kontakt and SampleTank)—and, of course, every Win10 upgrade since its debut. At this point I can’t narrow down what is causing the PACE service to need restarting (even as it displays “Automatic” in the Control Panel).
