SQL 2008 Install: Getting around the 3.5 .Net Error message

When trying to install SQL Server 2008, I was running in an error message saying that .NET 3.5 wasn't installed and the installation couldn't go on. Of course, .NET 3.5 WAS installed.

I had run into this problem before, I was going blog about it, but I forgot. :S

So here I am, blogging about it now. I remembered that a file was erased or overwritten. But I couldn't remember exactly what.

The solution is to download dotnetfx35.exe and replace this file with the one that SQL Server 2008 ships with. I couldn't find the original post where I saw this solution, but I found this link that talks about it:
