Installation of MYSQL: error code 0x800c0005

Hi,
I have a simulation of the Enterprise Network with the VMware. It is an INTRANET only (Do not access to the Internet). The Simulation is as the followings:
1)      Domain Controller
•      It is a Windows Server 2008 Enterprise SP2
•      It is at LAN 1 (10.10.10.0/24)
•      It also functions as The DHCP server, DNS server
•      The IP address is 10.10.10.10; the name is “DC1-W2k8”
•      The Domain name is Boba.com
2)      MYSQL_TRIAL  server
•      It is also a Windows Server 2008 Enterprise SP2
•      It is at LAN1; I assigned the IP address for this server of 10.10.10.50
•      The name of this server is MYSQL_TRIAL
•      This server is able to join Domain of the Boba.com; so its FQDN is MYSQL_TRIAL.Boba.com

3)      Installation of MYSQL
•      The goal is to install MYSQL server at MYSQL_TRIAL
•      I use “ MYSQL Installer 5.5.29 “ (as suggested by EE Experts)
•      The system needs the .NET Framework 4.0 for the installation
•      I have downloaded the .NET Framework 4.0, but during the installation, there is an error message like this:
.NET Framework 4.0 has not been installed because:
Download failed with the error code 0x800c0005
For more information please see the log file
I herewith attach this log file (please see the attachment)

4)      Any help?
5) Thank you
