When attempting to install Vivado using the web installer, I am asked to provide my Xilinx login information.
After doing this, the login authentication still fails with the following message:
You must provide a valid xilinx.com (including full export compliance) user ID and password to continue the installation process.
When authentication fails due to an invalid username or password, you should see the following pop-up message.Some customers have experienced an issue where the Vivado Web Installer returns a message about validating the private certificate even though their User ID and Password are correct.
For Vivado Design Suite 2014.x, there are 3 full product installation images available on http://www.xilinx.com/download
Note: For Vivado 2014.x, download images are now zipped as well as tarred in order to limit the possibility of a corrupted archive.
