windows - How to append to the PATH variable in Visual studio 2013 -


i want append value path environment variable. thought should easy not working in developer command prompt vs2013. have tried following commands: 

set path = c:\temp;%path% //no quotes set "path = c:\temp;%path%" //quotes around set path = "c:\temp;%path%" //quotes around value set path = "c:\temp;"%path% //quotes around new value appended

i have looked online , seems suggest first or second option above when 

echo %path%

i dont see c:\temp in path variable.

any appreciated. on windows 7 , work in python needed install quantslib. so, have go through visual studio.

the environment block captured when process starts, means visual studio won't see updated path unless restart it.

editing path command prompt possible, easier way modify environment variable:

  1. right click on "my computer"
  2. click on "properties"
  3. in left-hand column, select "advanced system settings" advanced system settings
  4. click on "environment variables..." button. enter image description here
  5. under "system variables" select "path" variable, click "edit...". enter image description here
  6. edit path heart's content, click "ok" enter image description here
  7. press "ok" on 2 open dialogs. if program that's running needs path, you'll have restart program. if want sure has new path values, reboot computer.
