What is this commercial marketplace?
This "Commercial Marketplace" is a portal for the apps published on the Microsoft Commercial Marketplace, including Microsoft AppSource and Azure Marketplace. You need to sign in with a work or school account to access the core portion of this portal. Here you can download apps, manage subscriptions purchased from the Microsoft Commercial Marketplace, and assign purchased licenses to end-users. You can also manage your commercial marketplace subscriptions via the Microsoft 365 admin center.
We also published some apps on the Microsoft Store. For those editions, you subscribe using a personal Microsoft account, download and install from the store, and manage your subscriptions using your Microsoft account. So, this portal for the Microsoft Commercial Marketplace system isn't for you if you purchase from the Microsoft Store.
Why are there two purchase links?
The apps published on the Microsoft Commercial Marketplace support two license management systems: Microsoft 365 Admin Center and the licensing system running here on UniformSoftware.com. The two purchase links point to two different editions that are bound with different licensing systems.
No matter which licensing system you choose, the download links are the same.
