This could be happening due the following 2 reasons.
1. When you use Windows Update or Microsoft Update to install updates, you may receive Error code: 0x80070490 if the Component-Based Servicing (CBS) manifest is corrupted.
2. It is also possible that there are some issues with the certificates verification. In case it is due to the missing certificates from the “Certificate Root” follow the second resolution listed below.
1. Please follow the steps documented at http://support.microsoft.com/kb/958044
2. To update the root certificates this KB update needs to be installed: http://support.microsoft.com/KB/931125. This is best done through the ‘Microsoft Update Catalog’ page: http://catalog.update.microsoft.com/v7/site/Home.aspx.
Click on the link to open the page and then search for "931125" and you will see several updates listed; select the correct update according to your operating system and OS architecture.
A reboot may be required. Once this is done, you should be able to Visual Studio 2012 without any issues.
