# Description

The current windows installation does not support pip installation of
isaac sim in venv as it only checks whether a conda environment is
enabled or assumes that a symlink to isaac sim is used. This change adds
support to check for system python when isaac sim is installed via pip.
In addition, isaac sim variables at conda environment startup should
only be assigned if isaac sim is installed from binary. This change
addresses the need for when pip installation of isaac sim is used in
conda.
