Well, maybe you are trying to install qualcomm augmented ndk on your system, and you are changing the path from my computer to change the setting:
my computer-> properties->advanced->environment variables user my computer-> properties->advanced->environment variables form your computer name select temp path than select edit and remove the additional add path after ";" and do not leave the "%USERPROFILE%\Local Settings\Temp" click "OK" so that your computer goes into an eclipse and starts your emulator, it will work.
