Open a CMD Prompt as administrator (right click cmd.exe and select Run As Administrator)
1) cd\C:\Windows\Microsoft.NET\Framework64\v4.0.30319
2) aspnet_regiis -r
3) Go to IIS ADMIN
4) Select Default Web Site
5) Doble Click ISAPI Filters
6) Doble Click v.4.0.30319 and remove the extra backslash between v4.0.30319 and aspnet_filter.dll (just check if aspnet_regiis won't work)
The root cause of the problem was the setup of older .NET Framework on Windows 2008 R2
bye
