Installation problem

When I had installed SQL 7.0 and about 99% completion,
the CD ROM drive is out of order and I had to end the
task.
Then I tried to uninstalled through add/remove program
but it is not successful.
Then I reinstalled SQL 7.0 again but the below messages
appears;
" There are files in the installation folder that do not
correspond to an existing installation listed in the
registry."
What has caused this? How to solve it? Please advise!Have a look at this article to see if it offers you any more information.
