Android Studio doesn't start, fails saying components not installed -

-

i have installed latest version of android studio google. after launching it, tries download packages.

after while shows following error.

the following sdk components not installed: extra-android-m2repository, tools, addon-google_apis-google-21, android-21, sys-img-x86-addon-google_apis-google-21, source-21, extra-google-m2repository

i couldn't rectify error, though pressed retry multiple times.

anyone can suggest solution!

i had been facing similar problem in windows 7 , got below problems while running android-studio shortcut start programs menu first time.

screenshot_1

solution : run administrator

the problem due write permission in windows c: drive , access denied message displayed. running program administrator downloads necessary components , can start android studio ide.

android studio - setup wizard success administrator

update:

these permission issues doesn't seem exist in android studio latest versions(checked in 1.3.2 in windows 10) , works without "run administrator" commands. if still have problem old/latest versions might firewall , proxy issues. in case check out other answers.
