Thanks for the prompt replies
Hi
This problem came to light when the security ran out, and I had to Instal new. I find that the message appears whatever I try to instal or uninstall. I don't know how long the problem has existed, the laptop is not used very often, my desktop is my main pc. I have tried everything I can with my limited knowledge. Nothing else is running on the laptop as far as I can ascertain.
