Windows 7: .NET Framework 4.0 Will not Install on Win 7 64(error code 643)

.NET Framework 4.0 Will not Install on Win 7 64(error code 643)

Hi, everyone. I'm new here but really hoping that someone can help me because I'm at my wit's end with this. My problem is that I cannot get the .NET framework 4 to install for anything.

On Friday night I began installing Sharepoint Server 2010. Below are the following related products I had installed at the time:

- SQL Server 2008 Express
- SQL Server 2012 Developer
- Visual Studio 2011 beta
- Visual Studio 2012 RC
- .NET Framework (All installed through 4.5)

I had a lot of problems getting Sharepoint to install since I'm on Windows 7. I ended up having to download the EasyScript on MSDN which appeared to finally work by installing all the prerequisite files that were needed. However, it installed Visual Studio 2010 Trial on my machine which then prompted SQL Server 2012 to ask for the Visual Studio SP1 before it would run. Thus begins all the frustrations that have haunted me this entire weekend.

I cannot get VS 2010 or SP1 to install for anything. It is giving me an error every time (error code 643 - .NET 4.0). I have tried everything I can think of at this point. This is what I have tried:

- All Windows Updates (Visual Studio 2010 SP1 keeps failing)
- Uninstalled all .NET Framework files, ran .NET Framework Cleanup tool
- Ran Microsoft 'FixIt' tool for MSI files
- Uninstalled all Visual Studio versions
- Tried installing standalone .NET files
- Tried reinstalling Visual Studio 2010

Here's a screenshot of the failed install on VS 2010:

I also ran the collect.exe tool to gather the error log files but am not sure what needs to be posted as the error log files are VERY long. Here is a snapshot of one of them (I have many as I've been trying to get this installed all weekend):
