How to Avoid DLL Errors on Windows

Under some circumstances, Windows Anaconda users may get unexpected errors about DLL libraries for scipy and other packages not being found. If so, the setting below may help.

For a single Anaconda Prompt session use:

set CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1

For a permanent change that will also affect Anaconda Navigator use:

setx CONDA_DLL_SEARCH_MODIFICATION_ENABLE 1

The second version adds the entry to the Windows list of environmental variables.
