android eclipse adb,Android Problem: Eclipse cannot find ADB.exe

First, I know this problem has been asked before, namely : Could not find adb.exe on my tools folder

but I tried every answer given and none work (even the accepted answer).

My problem is that I updated the Android SDK and now Eclipse cannot find adb.exe. I know where it is, it is in platform-tools directory, but I can't get Eclipse to read it from there. I updated the path.

Now what has happened is, in all my projects the asset folder is empty, meaning there is no android jar file.

Also, clicking on the SDK update manager from inside eclipse does nothing. I have no idea why.

Lastly, if I try to install new software in Eclipse (ADT update?) it wont allow it.

In the project -> preferences tab I get the following message:

Could not find C:\Program

Files\android-sdk-windows\tools\adb.exe!

I'm working on Windows 7 with Galileo eclipse.

Can anyone offer any help?
