Hi:
It also depends on the age/bitness of your computer. If you do NOT have a 64 bit machine with Virtualization enabled at the BiOS level, then University Edition is not an option for you. Older 32-bit machines cannot run SAS University Edition. The University Edition install is actually 2 downloads -- you need to download and install the hosting software (either VirtualBox or VMWare Player) and THEN, you need to download the Virtual Machine itself and install the Virtual Machine in the hosting software. Even if you have a 64-bit machine, if virtualization isn't enabled, you may need to fiddle with BiOS settings to make it all work.
If you're not into installing software and you have a decent Internet connection, SAS OnDemand for Academics is a zero-download way of using SAS. You will need to set up a SAS Profile (but you need to do that for either method). But then, after you set up your OnDemand account, you just need to open a web browser to go to the welcome.oda.sas.com web site in order to log onto the OnDemand Control Center and then click on the SAS Studio icon.
Both options will work for you for now, it really depends on your your computer setup and your tolerance level for doing downloads and installs. The SAS OnDemand alternative is zero-download, but you need a stable Internet connection. The University Edition alternative is 2 downloads but after you're done (and assuming you do the configuration correctly), then you don't need an Internet connection to use.
