That's really strange.
EViews 11 Beta only talks to Python that you already have installed. It doesn't change any environment variables, or path settings, or really anything related to an installation of Python. It also doesn't install any version of Python for you. So I'm not sure what could've caused your issue.
When the beta runs, it does try to read the registry settings to find the path locations of your Python installations, but this doesn't really work for Anaconda users as it don't put any information about your various Anaconda python environments (other than the base environment) into the standard Python registry location.
When you encountered a problem with Anaconda not starting, did you already try running the Beta and connect it to Python? If so, did the EViews connection to Python work? And was XOPEN active when you tried to run Anaconda Navigator? Install our beta using a zip file instead
Here's a link to a zip file
that contains the latest EViews 11 Beta. Please try downloading this zip file, unzip either the 32-bit or 64-bit folder to your desktop, then run the main EViews executable (either EViews11Beta.exe or EViews11Beta_x64.exe) to launch the beta. Once running, try running Anaconda Navigator.Register EViews 11 Beta components
If that works (which it should), try running the
command from the EViews command window (type it in and hit Enter). Then click the Yes (All) button to re-register everything. Once you see the success message, close the dialog, then try restarting Anaconda Navigator again.Finally, try running XOPEN
Assuming everything still works, please try connecting to Python from within EViews. To do this, go to the Options menu/General Options/External program interface and double-check the Python home path. If you don't see a valid value in this dropdown, click the [...] button next to it and select the appropriate Python home directory (the Python home directly is usually the folder that contains the python.exe executable). Once selected & verified, close the Options dialog, then type in the command:
See if EViews can connect to Python and a log windows appears. If it appears, type in a few python commands below the log window and see if Python responds as expected. Now try restarting Anaconda Navigator.
