That's weird because I've just downloaded the application and the process went through without any problems.
The first thing that I recommend doing, in case you haven't already, is making sure that you have enough free storage space on the partition where you're downloading the file. Even if there's enough space, you can try changing the download location to a different partition just in case there are some errors with the drive that you're currently using.
If that's not the problem, then try deactivating your download manager in case you're using one. Lastly, you might want to use a different browser such as Chrome, Firefox or Opera and see if one of them can complete the download process.
