This is what comes up any time I start up Anaconda Prompt -
Python:
    \Xtralien was unexpected at this time.

I am guessing it's because of a conflict with an old Xtralien python installation that I had and forgot about. I uninstalled that and reinstalled Anaconda but it hasn't resolved the problem.

You have to remove the old xtralian references in the PATH. Its at the end of the PATH definition.

I think there's system dialog where you can change it for the system or the user which is described below for Java as an example:

https://www.java.com/en/download/help/path.xml

You need to open the System Panel and go to advanced settings:

Windows 10 and Windows 8
  1. In Search, search for and then select: System (Control Panel)
  2. Click the Advanced system settings link.
  3. Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
  4. In the Edit System Variable (or New System Variable) window, specify the value of the PATHenvironment variable. Click OK. Close all remaining windows by clicking OK.
  5. Reopen Command prompt window, and run your java code.
Windows 7
  1. From the desktop, right click the Computer icon.
  2. Choose Properties from the context menu.
  3. Click the Advanced system settings link.
  4. Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
  5. In the Edit System Variable (or New System Variable) window, specify the value of the PATHenvironment variable. Click OK. Close all remaining windows by clicking OK.
  6. Reopen Command prompt window, and run your java code.
