Adobe Acrobat Writer 50 Link

Assuming the user meant Adobe Acrobat, maybe the "50" refers to version 50? But I don't recall version numbers going that high. Adobe Acrobat typically numbers versions like 9, 10, DC, etc. Maybe there's confusion with another product. Let me consider that Adobe Acrobat might have different editions: Pro, Standard, or even the online service, Adobe PDF Online.
