I think elicenser being a 32 bit application maybe a problem.
After updating to windows 10 1903, elicenser didn’t find itself and I couldn’t run Nuendo or Wavelab for hours. Then I had to uninstall the elicenser and then reinstall it, then click maintenance. But by that time, groove agent se 5 could not be loaded with existing sounds in existing projects. I had to add new tracks of the groove agent but previous sounds were all gone as it couldn’t even open the GUI. Mysterious as hell. On top of all that mystery, elicenser now installs an earlier version only, no matter how many times I download and install the latest version.
I think Steinberg should really look into the elicenser mechanism and make it 64 bit perhaps.
