Answer 1

Your error "Error 0x80070002: Failed to start the process" is a Windows Update error. Read here:

When you post in these forums, it is also very helpful if your tell us your Windows version and supply complete install logs as follows:

Please collect your install logs with this:

Answer 3

Unfortunately, the install does not start, so there is no log.

For the prep error you described (Error 0x80070002: Failed to start the process), you can try the steps in the answer in this thread:

Answer 4

Nothing helps. I can hardly run any programs without Framework 4.0

Answer 5

The remaining option is to reinstall your OS. Probably not something you want to do, but sometimes the only effective solution.

Answer 6

Reinstall my OS? What is that, and how do i do that?

Windows Update had an update for .Net Framework 4.5.1. At least i know my computer can run .net framework 4.0. The installation also failed with Windows Update.

Answer 7

"Reinstall my OS? What is that, and how do i do that?"

Your Operating System (Windows 7).

Answer 8

Hi BjarniP,

Please refer to this thread:https://social.msdn.microsoft.com/Forums/vstudio/en-US/22e1b37b-b4cc-4c48-a3ba-2737b0ad12a2/im-having-trouble-installing-microsoft-net-framework-4-on-windows-7-64bit?forum=netfxsetup

Read the step 2 :

2. Before running the installer, apply irarab's fix as follows:

"I went to "C:\Windows\Microsoft.NET" there is a directory called "assembly".

I looked in the directory and found some subdirectories with lots of old dot net 4 files. I renamed the directory assembly2 and tried to install Dot Net 4 and it worked!!!!

(You can't delete the assembly directory unless you take ownership of it but you can rename it.)"

Best regards,
