When trying to install SCE 2010 following problem arises. Can not continue the installation, there is no service of IIS. Naturally the service is installed. I look at the website technet. Issue: If Internet Information Services (IIS) was installed on the computer after the Microsoft .NET Framework 2.0 was installed, you must reregister Microsoft ASP.NET 2.0 before you install Essentials 2010. Workaround: Follow these steps: Open the Command Prompt window. At the command prompt, open the following directory: %WINDIR%\Microsoft.net\Framework\V2.0.50727. Type aspnet_regiis.exe i to reregister ASP.NET 2.0. I do it well for x86 and x64 version. So no result. IIS service must be installed. Windows server R2 standart x64. Please help solve issue. Regards

Hello, Is this server a clean built of Windows Server 2008 R2?

Depending on the version of the operating system, setup and configuration log files are located in%LOCALAPPDATA%\SCE\LOGS. To locate these log files, click Start, click Run, type %LOCALAPPDATA% in the box, and then click OK or press ENTER. Please post the details of the error message to help us to move on.

I do not know what it was a mistake, but corrected that. Initially I installed IIS by default, without changing or adding the role service. Then I added all the role services, and once again re-registered regiis and installation worked. Thanks for help. Regards!
