.Net Framework 3.5 (offline) installation failure is not detected about autospinstaller

Yep if you want to be covered for both Win2016 and Win2019 make sure these are in your \sxs\ folder:

microsoft-windows-netfx3-ondemand-package.cab microsoft-Windows-NetFx3-OnDemand-Package~31bf3856ad364e35~amd64~en-US~.cab microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab

I just got a similar error with Windows Server 2019, SP2019 and AutoSPInstaller 3.99.60.

  - Installing Prerequisite Software:
  - .Net Framework 3.5.1 from "\\ctadev03\devteam\SP19\2019\SharePoint\PrerequisiteInstallerFiles\sxs"...

Done.

I had dotnetfx35sp1setup.exe in the 2019\SharePoint\PrerequisiteInstallerFiles\sxs\ folder, but this doesn't appear to be the version that Windows Server 2019 wants. If I run it manually, it says to use PowerShell or the Server Manager.

When I run from ServerManager, it want's a path to the install file(s) and looking at the Windows Server 2019 install media, it's looking for something quite different:

microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab
Microsoft-Windows-NetFx3-OnDemand-Package~31bf3856ad364e35~amd64~en-US~.cab

This is exactly what I was looking for to make it a Full offline Install.
Thank You
