Once the ISO file has been downloaded, you need to burn it on a blank DVD-R disc using any burning software.
If you don’t want this option probably because you have a slow internet connection or usually have bad connections, you can download the ISO file from Microsoft Visual Studio 2010 SP1 DVD ISO. This option requires a stable internet connection because the download is over 1 GB in size and a little problem with the connection will reset the entire installation process back to the beginning. Downloading this installer requires an internet connection during the entire process of the installation.
One of the available options is to download the web installer from Microsoft Visual Studio 2010 SP1 Web Installer. Unfortunately, there is no official standalone installer for Microsoft Visual Studio 2010 Service Pack 1 to make it more convenient for you to install the upgrade or to perform the installation. That message is actually not an error but a note from Microsoft informing you that other or not all Microsoft Visual Studio 2010 applications on your computer have been upgraded to Service Pack 1 and because the upgrade is incomplete all programs associated to Microsoft Visual Studio 2010 will not work until the rest are upgraded to Service Pack 1.
