"The Application Data folder for Visual Studio could not be created" during installation

A few days ago I had a crash of my computer and since then i am unable to succesfully install Visual Studio 2012 Ultimate.

During the setup a error screen comes up with nothing but a message "The Application Data folder for Visual Studio could not be created". Searching for this only results in the same error message but only after installation where Visual Studio cannot be launched.

This is different for me since I am able to run it. But i am unable to e.g. create ASP.net VMC projects. Some things run fine. Others just fail at the start.

Uninstalling the whole shizzle separatly came to that the error may be in the SQL server package. Since this error came up while uninstalling the SQL shizzle.

I'm not sure if this error is a common issue, but it's really annoying since I will be learning ASP.net VMC4 at school for the coming 5 months.

This is the error message i get. I only moved the window a little bit the let you take a look at the package. http://i.imgur.com/V0GtnLQ.jpg

Below there is a fragment of log files where installation packages failed. Hope they are handy.

The problem was solved by formatting my pc and starting all over again. I still don't know the real problem but this solved it.
