Environment: Windows server 2008 Web Edition + IIS7 + .net 3.5sp1. I had following error while trying to install SQL 2008 express: It happens after click on “Install” button, when setup collected all necessary info, such as installation path, db server settings, etc. Google found 20+ topics on forums, newsgroups and ms connect, but they hasn’t solutions, or solution is for CTP version of SQL 2008. I start setup with admin privilegies, update windows server, repair .net installation – it’s useless....
