Way to check installation integrity and repair missing files? [solved]

Short version is I was able to install, activate, and run Cubase despite some corrupt extra content files (by manually extracting the installer using 7-Zip). What’s the best way to try and repair the missing files? Download the installer again and hope for better results? Is the full installer is available for manual download?

Edit2: Ended up using JDownload 2 to download and extract it to finally install it successfully.
