Problem to update to 10.0.15

I`m getting message "The instalation source for this product is not available. Verify that the source exists and that you can access it.
Error code: 1612

Please help:)


Make sure, you have Cubase 10 Full Installer installed. Make sure, you are installing the same version/derivative (so if you own Cubase Pro, install Cubase Pro update, if you own Cubase Elements, install Cubase Elements update). Is your Cubase installed on the C (system) drive?
