Just purchased 10.5 and can’t get past the above no matter what I try. I’ve downloaded the full installer for 10.0 and re-installed 10.0. Then I’ve tried both the 10.5 updater and then the full 10.5. Both report the same error:
An installation package for the product Steinberg Library Manager cannot be found. Try the installation again using a valid copy of the installation package ‘Steingberg Cubase Update’.
Any ideas what else I can try?
