Quote System Requirements part of 'buy page' : Required hard disk space depends on how many products/libraries you want to install. To install all products and libraries, 1100 GB free disk space is required. Please note: The installation process may temporarily require up to 80 GB of additional free disk space on your system-drive – even if you're installing Komplete on an external hard drive. This number significantly decreases for smaller products, or if products are being installed one by one.
