Write access denied to registry?

My programme updated today to 1201 and after the pop up saying it had updated, there was a pop up in the background saying write access denied to the registry? I didn’t get time to read it.

I am using Vista Ultimate SP1.

Does anyone know what this was?

I think it best to stick to the other topic that you found relating to the same problem.
