Well I know a little about computers as I have been a programmer for 29 years.
I have fix the IE8 problem by re-installing it and making this post.
I firmly believe:
Webpage error details

Message: Element not found.

means that the web page to add search engines: Element not found means
the web page itself is broken, or broken links; this web page appears fixed
now;
maybe the re-install fix the problem.
In the end though, do not let MS on your compter remotely, without a proper
backup; and I found there support completely unable to solve or trouble shoot
this problem. I have found that it is best to argue with MS only for 20
minutes
if they can't fix the problem, then fix it yourself or ask someone else.
