I have installed Android Studio (version 1.5.1, build 141.2456560) two times today, on two PC computers, and I have seen this error twice now. In other words, the same error appeared on both computers, both of which were running Windows 10 Pro (x64, version 1511, build 10586.164).
The following SDK component was not installed: android-23
What is the problem? How do I resolve this?
