When i download the Designer/Photo/Publisher Software from here (e.g. -us/update/windows/publisher/1/) it requires a product key wich i can not receive, because its not in the purchase mails or in the order list from microsoft purchases and the links don't work.
Open the Microsoft Store app on your PC. Click Library, which will show you the apps you have purchased. If they are not in the list, click Filters and Sorting, and turn off the option that restricts the listing to the apps you have installed.
The products have been withdrawn from sale and Microsoft make them hard to find even if you are an owner. They can be found in your "Library" of purchased products (as Walt correctly suggests), BUT I have just realised that for people like you these links will also work
Affinity Designer V1 Store protocol link: ms-windows-store://pdp/?productid=9nblggh35lrm
Affinity Photo V1 Store protocol link: ms-windows-store://pdp/?productid=9nblggh35lxn
Affinity Publisher V1 Store protocol link: ms-windows-store://pdp/?productid=9nblggh35lzr
You'll find the Affinity Apps you bought in the MS Store App under Library. There is a drop-down selection "Sort and filter". There is a selection point "Show only installed products". After you have unchecked the box, the Affinity program(s) should appear in the list of apps
