Hi,
I am using Windows 10 Pro.

I tried to edit a C++ Program in Fusion 360.

I got the message " The File C:\Windows\MicroSoft.Net\Framework\V.2.0.50727\Microsoft.Vsa.tlb could not be loaded. An attempt to repair this file failed, because the file could not be found. Please insintall this program.

I uninstalled Microsoft.asp.net.mvc-2 Visual Strudio 2010 Tools.

Uninstalled Fusion 360. Reinstalled it.

I downloaded Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package MFC Security Update.

It said the following feature was successfully installed: .Net Framework 3.5(Includes Net.2.0 and 3.0).

I downloaded dotNetFx40_Full_setup and tried to installed.

Windows responded in the Microsoft .Net Framework 4 setup saying that " your installation did not occur because it is already part of this operating system. You do not need to install it."

But when I try to edit a C++ program, Visual Studio is reponding by it says the Visual C++ Project "SketchLines" is targetting ".Net.Framework,Version v4.0 which is not installed in this machine.

Now I am stuck.

Please Help.

    Hello @Thurairajah Perampalamoorthy ,

    I would recommend what it helped when I had the same issue:

    I started Visual Studio Installer ("C:\Program Files (x86)\Microsoft Visual Studio\Installer\vs_installer.exe") and clicked Modify button.

    On Installation details on the right I first removed under ASP.NET and web development > Optional:

    .NET Framework 4 – 4.6 development tools

    .NET Framework 4.6.2 development tools

    and any other

    Then clicked on Modify and waited for VS to remove those.

    Then I did the opposite steps again:

    I started Visual Studio Installer ("C:\Program Files (x86)\Microsoft Visual Studio\Installer\vs_installer.exe") and clicked Modify button.

    On Installation details on the right I added under ASP.NET and web development > Optional:

    .NET Framework 4 – 4.6 development tools

    .NET Framework 4.6.2 development tools

    and any other I needed

    Then clicked on Modify and waited for VS to add those.

    Hope it helps
    Luis P
