Itunes has invalid signature

(Like many of my technology postings, this is really here for my own notes on problems I run into, the solutions I try and what works when. They are updated as I learn.)

After uninstalling Itunes with Revo Uninstaller, I followed these steps from Gheeda Al-Zubaidi. 

To solve this issue:

1. I right clicked the installation file

2. Went to properties

3. Clicked unblock

Then:

1. From the start button, searched for "uac"

2. Clicked "Change User Account Settings"

3. And dragged the bar to "Never Notify" (needs restarting)

4. After restarting, I ran the installation as administrator again, and it worked!
