Android sdk Tools, Revision 12 does not update

I'm fairly new to 开发者_JS百科Android and today I fired it up and found a new update. I decided to install it, but it fails every time and display this message:

"Done. nothing was installed.

Downloading Android SDK Tools, revision 12 File not found: C:\Program Files (x86)\Android\android-sdk\temp\tools_r12-windows.zip (Acces denied)"

I turned of my AV and any other program, turned off and on the SDK Manager but the error still appears. Can someone help me out? Can I update it without using the SDK Manager?

Thanks in advance.

Are you updating through Eclipse? It sounds like a permissions issue to me - try right clicking and selecting run as administrator before updating.
