While trying to setup a clean development computer, I ran into all sorts of installation problems with SQL 2008 R2. “Invalid operation” and “System version=184.108.40.206” not found. After trying all sorts of install/uninstall combinations, I decided to format the disc, reinstall W7.
Seems like that did the trick and now I am blaming Visual Studio 2010 (with .net 4.0) for the installation problems.
This being a completely blurry blog entry, I will provide logs and what the exact error is if anybody asks.
