hey viewers,wanted to install CIS 3.9 as u noe d.On the 1st trial everything went well untill the scanning and then an error occured and then on the following tries they kept on asking me to uninstall which is something i’ve done.Have triple check and there is no files to be found but the ques keeps on popping out and there seems to be no reply when click yes or no on that part.Some help would be excellent. 
Check out this post by Dennis2 and see if it helps… If I understand you correctly you tried to remove CIS and now you can’t install it? You believe CIS is gone but the popups suggests something else? =)
