If you are determined to test the waters, you need to know what a fake looks like. Legitimate file listings for portable software usually follow these rules, whereas scams do not:
Also, the "1" in the name is ambiguous. Maybe it's version 1.0? Or a specific release? Without more context, it's hard to say.

Also, "Link" could be a feature in Microsoft Project. There's a feature called Project Link or Task Link, but I'm not sure. Alternatively, the user might be referring to Microsoft Project Link, which is a different product. Wait, Microsoft Project Link is actually a real product, but it's not widely known. It's part of the Project family but is more for linking tasks across projects. However, I'm not certain about the portable version.
