I installed SFP 12 yesterday on a Win 10 machine - recent spec. About a third of the way into the install it hung. Complaining that there was a problem with eLicenser needing updating. As eLicenser is a Steinberg product (for my Wavelab and Cubase) I thought this must be an error. I tried twice more to install same problem. I visited the Steinberg page - downloaded the latest eLicenser Control centre and installed it. Then I installed SFP 12 without a problem!!
