.NET Framework 4 Multi-Targeting Pack Unable to Uninstall

Question

I'm currently trying to install Atmel Studio 6.2 with .NET and the Visual Studio Isolated Shell 10.0 portion of the install is giving me some trouble.

When I attempt to install Atmel Studio, it tries to install .NET Framework 4 and immediately fails with the resulting log:

My first reaction was to try and uninstall/reinstall .NET Framework 4. When I attempt to uninstall it, I receive the following error:

The path 'C:\\Users\\MyUser\\appdata\\local\\temp\\sit31981.tmp\\wcu\\mtpack\\NetFx_DTP.msi' cannot be found. Verify that you have access to this location and try again, or try to find the installation package 'NetFx_DTP.msi' in a folder from which you can install the product Microsoft .NET Framework 4 Multi-Targeting Pack

I've tried searching around my computer to try and find this file with no luck. I've also done some research to try and find the file 'NetFx_DTP.msi' by itself with no luck there either.

If anyone has any tips on how to possibly solve this, it'd be much appreciated. Thanks!

Answer 1

For Windows 10 / Server 2012R2:

• Download the Windows 7.1 SDK ISO image
• Unzip it
• Run Setup\\MTPack\\netfx_dtp.msi EXTUI=1

You should now have a %programfiles(x86)%\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.0\\ folder with the 4.0 stuff.

This Microsoft Support post addresses the issues I was running into. FixIt was able to reset the corrupted registry entries and get everything back to normal!
