Thank you for writing us today about the publicly-available computers.
For your security and that of others, the ability to install third-party software has been disabled. This makes it unlikely that a malicious user could install a key logger or other program with the intent to defraud other users. In the case of iTunes, it also ensures the security of your music library and iTunes store credentials.
While the computers we provide do not allow iTunes, you can freely open iTunes and access the store from other devices by connecting to our wireless network. Additionally, much of the iTunes store can be accessed from the web. The easiest way I've found to do this is to search Google for the artist/album/song you're looking for followed by the word 'iTunes'.
Thanks again for writing us. Have a great day.
