Installation crashes. SQL Server 2008 r2 Express

I'm trying to install SQL Server 2008 R2 express on my fresh win 7 ultimate x64 install. Every time the installation starts, it crashes with the following message:

Did anyone had similar pr开发者_C百科oblem? how did you solve?

So here are some ideas to try if they help. First, I assume that you're installing the 64bit version of SQL Express? Also, the faulting module is a .NET component, so maybe try repairing .NET 2.0? Finally, I'm not sure this would work, but as a last-ditch effort, you could reboot to safe mode and try the installation from there. I know these are just shots-in-the-dark, but if 300 billion web pages don't have the answer, then maybe some random tests might get lucky.

In my experience SQL express installs tend to crash (well over the past 5 years anyway) when you install direct from the web. I would allways recommend downloading the complete install package, then runing it from a local folder. Everytime the direct web install has crashed for me (probably around a dozen time now accross various versions), downloading the full install and then running it locally has lead to a clean install.
