Cubase 10 Additional Content won't install

Thanks for getting back Martin. Good suggestion but the installer creates the folder with no prior opportunity to effect permissions. I’m thinking also that since I use the admin account to install, the resulting folders would have read/write permission. The folder it creates has read/write permission but is empty. I try using the Library Manager but it is empty as well. The only option I have is to drag the contents from the download folder to the program folder after installation. And this results in many missing files.
BTW,I see that Wednesday is your 8th year anniversary on the forum. Congrats.
