Google Chrome is the primary browser used in our software quality testing laboratory, although cross-browser compatibility tests are performed periodically in other W3C-compliant browsers such as Mozilla Firefox and Microsoft Edge. The latest versions of these browsers are fully supported; older versions and non-W3C compliant browsers may inaccurately render buttons, text, and menus, for example. Javascript should be enabled in the browser. We receive many reports of users operating very old (unsupported) versions of Internet Explorer, and while some incompatibilities are noticeable, the system is largely functional and usable.

Microsoft Windows 10 or 11 is recommended, since Google Chrome's latest versions are fully supported on Windows 10 or higher. Again, many reports are received of users on older operating systems (Windows 7 and 8) which do not support the latest Chrome updates, so there is risk that using an outdated version of the browser exposes the user (and the brand/retailer client) to browser-related security vulnerabilities. That said, LINK is quite usable on these older systems. If users are downloading or uploading Excel files, we recommend Excel 2016 or higher on a 64-bit computer for the best experience. Some file downloads may fail with older versions of Excel (97-2003) due to Excel’s maximum row limitations.

Any local computing resources (RAM, storage, CPU) are irrelevant except to the extent the user may be uploading/download files from/to local storage, since all other processing in LINK is handled by the browser, server, and internet connection between. A high-speed/broadband connection (defined as a minimum of 25 Mbps download and 3 Mbps upload speeds) is recommended, but as with any web site, the faster the connection the more seamless the user experience. Our software testing laboratory routinely conducts performance testing with a 300 Mbps wi-fi connection speed to determine whether page loading times meet acceptance standards.
