Security and legality concerns

strictly uses native, official Microsoft API methods to download and assemble the configuration files, making it completely clean of unauthorized patching modules.

Here is the direct reason why:

Note that Microsoft Office 2013 reached end-of-support on April 11, 2023, meaning it no longer receives security updates even if installed via these tools.

While tools hosted on sites like AppNee are popular for their utility, users should always exercise caution.

System administrators and power users seeking custom Office configurations can use safer, transparent alternatives without running unverified executables:

Microsoft uses Click-to-Run (C2R) technology to deploy modern versions of Office. Standard Microsoft installers force you to install every single application in the bundle.

MAS is a free, open-source tool hosted on GitHub and recommended by many in the tech community. It supports modern, safer activation methods like Ohook (which "hooks" Office into a false activation state for permanent activation) and HWID (for Windows). Because it's open-source and widely used, its code is publicly auditable, reducing the risk of hidden malware, though the usual cautions about downloading from the official source still apply.
