Windows 10 comes with .NET framework 4.5 pre-installed, but many apps developed in Vista and Windows 7 era require the .NET framework v3.5 installed along with 4.5.
These apps will not run unless you will install the required version.
When you try to run any such app, Windows 10 will prompt you to download and install .NET framework 3.5 from the Internet.
Here is how to install it offline using DISM from Windows Kits for Windows 10.
Dism /Get-WIMInfo /WimFile:S:\Temp\install.wim
Dism /Mount-WIM /WimFile:S:\Temp\install.wim /Index:1 /MountDir:S:\Temp\offline
Dism /Image:S:\Temp\offline /Enable-Feature /FeatureName:NetFX3 /All /Source:H:\sources\sxs /LimitAccess
Dism /Image:S:\Temp\offline /Add-Package /PackagePath:S:\Temp\de-de
Dism /Image:S:\Temp\offline /Add-Package /PackagePath:S:\Temp\fr-fr
Dism /Image:S:\Temp\offline /Add-Package /PackagePath:S:\Temp\nl-nl
