.NET Framework 4.8 - How to check that the target system meets the minimum capabilities

[mihai]

Hi,

The list of supported client & server operating systems is listed by Microsoft here: https://docs.microsoft.com/en-us/dotnet/framework/get-started/system-requirements#supported-server-operating-systems.

I get this when matching that against the list from InstallAware X6:

Get Exact Operating System Version.png (31.89 KiB) Viewed 6945 times

However, I'm unclear on how to use the "Get System Settings" command from InstallAware to perform all these checks. First off, does this command mix client & server operating systems? E.g. will the “Get System Settings” command return true for “Windows Server 2012 R2” minimum capability on “Windows 10”? It would help to understand what it does under the hood - does it just compare the build numbers?

Thanks in advance.

Apparently not, because "Get System Settings" for the "Windows Server 2012" (build number would be 9200) capability returns FALSE on Windows 10 (2004, build number 19041). This is probably a good thing for the task at hand.

it's exactly as you say.

"Get System Settings" for the "Windows Server 2012" (minimum capability) will return FALSE when executed from any non-server version of Windows OS.

Thanks for the confirmation!

Here's what I have so far, for .NET Framework 4.8.03928. Does this make sense? Any feedback would be highly appreciated.
