Windows Update 7.2.6001.788 Fails to install

I cannot get my windows update to work correctly. WU 7.2.6001.788 tries to install itself and fails. I've changed the name of the software distribution directory to "erase" the memory of old updates and that worked but still no luck installing WU.

THanks in advance for your help.

Try installing the standalone package manually from here: How to obtain the latest version of the Windows Update Agent to help manage updates on a computer
