If you have a license for 2014, you should check out 2014.5. There were many updates and fixes.
Both will install onto the same machine (Mac and Windows) and use the same license. As you have been shown, the icons are slightly different—this confuses many users.
Find and place both icon shortcuts wherever you normally keep these. This will allow you to compare both versions to see if one is better for your use. For most, it is 2014.5.
