Can't installer .net 3.5 on Windows 10

ayi

Quand je try to install .net 3.5 I get the follwing message:

The following feature couldn't be installed:

.NET Framework 3.5
(includes .NET 2.0 and 3.0)

Error code: 0x800F081F

J'ai essayé with a standalone package and through Windows Features.

Mise à jour : Internet connection is fine.

ayi

Please open a invite de commandes (cmd.exe) en tant qu'administrateur and run la commande suivante to install .Net 3.5:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /Source:d:\sources\sxs /All /LimitAccess

(replace D: with your mounted Win10 ISO)

In some environment, DISM fails to fetch the file (Proxy, network policies). The DISM command takes the files from the DVD and you're fine.

Si vous êtes MSDN subscriber vous pouvez aussi download the Windows 10 Features on Demand ISO, mount the ISO, copy the Microsoft-Windows-NetFx3-OnDemand-Package.cab to C:\Features (or a different folder) and those commands:

DISM.EXE /Online /Add-Capability /CapabilityName:NetFx3~~~~ /Source:C:\Features

If this fails, run this:

DISM.EXE /Online /Add-Package /PackagePath:C:\Features\Microsoft-Windows-NetFx3-OnDemand-Package.cab
