Hello @eddymaoui,

OK, this seems to indicate an issue with our (anaconda) Python based GUI. My guess is that there is a related error message in the terminal window that appears when you run via the mcgui-2.5 link.

Could you try issuing the command "mcgui" via the mcstas-shell-2.5 window? Then I can have a better idea what is going on?

Best Peter

Hello again,

OK, as I assumed it is an issue with the python modules... What is the output of the following command if you give it in the same terminal?

python --version

Is there a chance you tried installing McStas behind a proxy server - or without access to the internet? If you were behind a proxy, try setting the variables

set HTTP_PROXY=http://your_proxy_ip:port
set HTTPS_PROXY=http://your_proxy_ip:port

Anyway try installing the python modules again using

conda config --add channels conda-forge
conda install mingw -y
conda install -c msys2 m2w64-gsl -y
pip install pyqt5 qscintilla mpld3 pyqtgraph pyaml ply matplotlib numpy tornado scipy pillow

(These commands are taken from https://github.com/McStasMcXtrace/McCode/blob/master/meta-pkgs/windows/python-install.bat.in)

Judging from the later issues, I assume you succeeded in getting McStas running? :-) Therefore I am closing this issue. :-)
