Java version 6 or higher of the Java Runtime Environment (JRE) must be installed to be able to open the Download Manager. See Chapter 3 of the TCIA User's Guide for more information.
Does Download Manager work with any browser?
Theoretically, yes. However, we principally test with Firefox, Chrome, and Internet Explorer. We also test with Safari (the default browser on most Macs), and it did work up to version delivered on Mac OS X version 10.8.3 (Mountain Lion). After 10.8.3, Safari will silently download the JNLP file used to launch the Download Manager, but will not automatically start the Download Manager program. Safari does not give the user any warning, so to the casual user it appears that the Download Manager link is broken. One has to go to the Downloads folder, find the JNLP file just downloaded, and then command | control | right click the JNLP file and select "Run" from the pop-up context menu to start the Download Manager.
Are there operating system requirements for Download Manager?
In theory, the Download Manager, being Java based, will work on any operating system. However, the Mac OS X operating system has been imposing additional security requirements on Java Web Start programs, such as the Download Manager, which make it difficult to run them without having administrative access to the Mac. In particular, the Gatekeeper function in 10.8.4 (Mountain Lion) and later versions of Mac OS X by default blocks starting third party programs that have not been either obtained from the Apple App store, or that have not been signed with an Apple Developer ID. This includes, naturally, Java Web Start programs such as the Download Manager. To get around this restriction, one can either change the default Gatekeeper setting, found in the Security tab of Apple System Preferences, to allow the running of 3rd party applications, or download the JNLP file used to launch the Download Manager, and then command | control | right click the JNLP file and select "Run" from the pop-up context menu. Note that either method requires either having administrative access to the Mac OS, or knowing the username/password of an administrator account, since the Mac will prompt for this information.

How many series can Download Manager download from a single shopping cart?
The Although theoretically there is no maximum number of series that the download manager can manage from a single shopping cart, we recommend limiting a shopping cart is somewhere around 3500. The limit is imposed by Javato no more than 3500 series. To determine how many series are in your basket at a given time, on the left nav at the top (under My Data Basket > View Contents) the number of series in a basket will display.
