Wow then it seems like you are one of the lucky few. It sounds to me like a very bad problem to have.
There is no need to uninstall them first. This error (99% of the time) is not due to those being corrupted, but one never having been installed. Since you don't know which one is missing, install them all and the problem goes away. That is the theory behind this fix.
I've tried all but the message does come up still. I'm rubbish with computers. Can someone help me please with all the steps to do 1by1.
Tks a lot
