URL Not Found Error in SDK Manager As of lately i have not being able to update / install SDKs from Android SDK Manager.

I get the following errors:

Preparing to install archives
Downloading Android SDK Platform-tools, revision 20
URL not found: C:\Program Files (x86)\Android\android-studio\sdk\temp\platform-tools_r20-windows.zip (Access is denied)

Skipping 'Android SDK Tools, revision 23'; it depends on 'Android SDK Platform-tools, revision 20' which was not installed.
Done. Nothing was installed.


I have given full right permissions on the directory that the SDK manager is installed as well as the temp directory
While android-studio was already running I tried to run "android.bat" at below location by right clicking and choosing run as administrator which ran SDK manager and download worked for me.  

C:\Program Files (x86)\Android\android-studio\sdk\tools\android.bat
