I had a problem with ERROR 646 and after searching the web couldn't find the answer to my problem. I then found FixCleaner, and after reading the advertisment, about all the things it would do, I downloaded and paid for it. I then tried for two days to remove the error that had been keeping me from downloading the Win7 updates I needed. I then sent 2 emails for a refund, and to this time and day, I haven't heard a word. So here I am regestering, and still trying to find someone that will send my $34.95 back to me. Does any one have an idea how I may do this?
