As one can see from the error message, what one actually should do is as following:
chmod +x path_CrimsonHigh/lib/py2-linux-x86_64/CrimsonHigh
The meaning is "give file path_CrimsonHigh/lib/py2-linux-x86_64/CrimsonHigh permission to be an executable one"
Moreover, if for any bloody reason one has to use sudo and therefore root password for this, that means that something is bloody wrong with the system configuration itself.
