Thank you for the information... Fyi. I ended up un-installing, then re-installing Protools. It still crashed. I for some reason decided to right-click on the shortcut on my desktop, then selected run as Administrator... It started Protools & I was then able to re-validate the installation...

Problem solved...

I don't understand why or how Windows update managed to corrupt only Protools but thanks allot Microsoft...

Thank you again for your input Sir.
