How do I fix Office 2016 installation error 30015-6(-1)?

1. Consider using an alternative to MS Office

If the Microsoft Office suite won’t install, why not change the office suite to a lighter alternative, that is fully compatible with Windows 10? Especially since there are a lot of cheaper, user-friendly, and more versatile solutions on the market. One of them is WPS Office. With more than 300 million monthly users, the suite’s popularity comes partially from its freemium model, as well as from the ease of use with the browser-like all-in-one mode. The suite includes 3 main tools –  WPS Writer, WPS Presentation, and WPS Spreadsheet, that are fully compatible with Microsoft’s Office Word, PowerPoint, and Excel, respectively; it also includes full support for PDF documents. With one single account, you get access to the entire suite, anytime, anywhere. All your work is automatically saved in the cloud, no need to save anything locally. As mentioned, the basic suite is free, with the possibility to upgrade to a paid plan, to have access to the full features. It’s worth a try!
