Hi Daria, 

Sorry for the trouble.  Just as a general comment, and because I see this too often, "I uninstalled and reinstalled it N times" hardly ever works.  I understand that it is a fairly easy thing to do, but it is rare for reinstalling to fix problems other than corrupted files or the occasional conflict between libraries.   There is no need to do that more than once.

A bug report like this is really hard for us to diagnose.   Like, why did an earlier version stop loading?   Something must have changed there. Do you have any idea what that could be?  Is that important?  

You say that you also uninstalled Anaconda and Python, implying you may have had a different Python environment installed.  If you install Larch from the installer or  GetLarch script, it will always install a completely isolated Python environment.  You can use an existing Python or conda environment if you want, but if you do that, you do sort of take responsibility for doing at least some troubleshooting of running Python programs.   

I'll assume that you installed from the provided installer. If you open your Anaconda Prompt for the version of xraylarch that you installed, you should get a prompt like:

    (base) C:\Users\yourname>

and you should be able to type "larix" there to start the Larix application.  You said that you see files in the Scripts directory, so that means that at least most of the installation work. If you get "larix is not a recognized command", then try to figure out why your Anaconda prompt is not set up correctly or set the Path to include the appropriate Scripts folder.   

If you get some other message, read and try to understand the messages printed out.    Is some package missing?  Perhaps 

        pip install missing_library 

will fix that.  If you don't understand the message, please post the entire message, preferably as text with reasonable contrast.  Shells on Windows often default to red text on a black background, which is very hard to read (at least, for me). Please do not post an image of that.  Copy the text and post that.

If Larix does run, then typing

     

      larch -m

will create the Larch folder on your desktop and include the shortcuts to starting the programs.  If it does not, then post the error messages.
