This question is mainly about installation of Sage, but I figured I'd give here a try: also in general I'm a bit confused regarding installation of Sage:
I went to the download page, after choosing the server close to my location:
sage-6.1.1.tar.gz
and downloaded it to my windows 8, 64-bit PC. However, the file is not opening (I double clicked on it in order to run it) in my PC, even after installing 7-zip, with which I could extract/convert it to a .tar file. What is your suggestion for opening it and getting Sage to work? I thought that its installation would be as simple as that of python itself, where I did not run into a opening/running problem.
Apologies if this is an irrelevant question for this site!
