Question

Search Engine Optimization

There are several files on the page for downloading (There is only one program page - on one page, program versions are divided mainly by OS. All of them belong to the software category ( schema.org/SoftwareApplication )
The page has a general description of the program and a description for each version. The
question is How to do micromarkup correctly.
Also, the question is how best to specify itemprop="description"?
Specify a general description or a description of each program separately? Or both?
Now we get this format (check via google)

Will it all get mixed up when indexing No, I do
n't want to make each version of the program its own page ...
It should also be said that the rating is general.
