# New Sage user on Windows - Module not found

Installed Sage 8.9 on Windows but am a brand new user. I loaded the source file I need to interpret/run (aes.sage) but when it begins to load, I get the below. The aes.sage file is open source code, so I suspect it's fine. Is something wrong with my environment? I can't seem to find any good help files on running Sage in Windows

Directly related - I cannot find the paths below (starting with "/opt...") in my install path for sage (C:/users/meyer/.sage) It appears these are there someplace....

Is there a simple "hello world" sage script to test and see if everything's working?

# ??? and thanks.

ImportError: No module named finite_field

I did find /opt....so it appears the files are there. Anyway, do I need to put my source file someplace else?

Hi BMeyer

I think you need to be more precise so that we can help you. did you install Sagemath 8.9 without encountering any problems? then when you click on the notebook icon on your desktop what happens to you?
