Note
IE can have issues downloading the CRT file appropriately; at times it will change the extension of the .CRT file to _CRT. Simply renaming the downloaded file extension will correct the issue. Testing this link via Chrome is recommended.
If the browser is able to download the CRT file correctly, you may see this warning shown below. Select "Keep" to allow the file to be downloaded.
