Okay, this is the developer version, so you can write your own software. To install this version, you must have Visual Studio installed beforehand.
Also, it seems to me (since you sent the confirmation link) that this is the translation package, so you must have first installed the English version.
What do you need?
Writing software in .NET 4.8?
Getting an existing software you have to work?
