# Why does Sage Math crash instantly? / Running .sage files?

Hello. First of all, I need to Mention that I am completely new to Sage Math and I have no idea what causes my problem(s), like seriousely, no idea. When I start SageMath, it instantly crashes, I don't even touch anything. I'm running Windows 10 and I downloaded the binaries, a virtual box and this sage-8.6.tar.gz file. I am sure that I must be missing something but I don't know what. Yesterday, I managed to get Sage to work, so in the terminal i could write simple commands like sage:4+3 and later, I reinstalled python. Now it does not work anymore. My original aim was it to have sagetex in Latex, but for some reason running the .sage file which is created with every document using sagetex doesn't do anything and sage does not compile my document. And yes, I did follow the instructions how to make sagetex known to tex. I have no idea how to continue, so many problems and i'm desperately trying to get things to work. (Feel like I downloaded half the Internet...)

You should provide additional information about your setup. Which steps did you follow to install SageMath. Which installation of latex are you refering to? (you did install latex in the virtual box?)

BTW, is there any reason why you use virtualbox? You could give a try to the windows binaries. They are much more up to date than the virtual box.

"Feel like I downloaded half the Internet..." That's probably part of your problem right there. Without more details we can't possibly know exactly what you did, how your computer is configured, or what the problem is. But usually throwing more downloads at the problem without understanding what you're doing is only likely to break more things and make the problem exponentially more difficult to untangle (for example you wrote "I reinstalled Python"; but Sage includes its own Python interpreter and should have nothing to do with other Pythons on your system). Did you install Sage using the executable installer? If so there's no need for virtualbox in the first place. And sage-8.6.tar.gz is just the source code...
