My computer updated yesterday to WIN10 1709. I had to reauthorize AD2, rescan all VST’s, re-select ASIO drivers and reestablish ‘Save As…’ pathways in Sonar, and to top it off, the eLicenserCC started coming up with an error code when I started Cubase 9.51.
I first updated the eLicenserCC, then ran the maintainence mode which couldnt complete step 6 for what ever reason. Error code then only came up with starting eLicenserCC, but it did allow me to open and save a new project in Cubase.
After reading this thread, I went back and ran eLicenserCC as ‘Administrator.’’ Finally Step 6 completed without issue! I know this doesn’t help the OP, but it may confirm some steps other users may find helpful to take. I did not have to uninstall and reinstall eLicenserCC.
