Just got a new computer a day ago. Downloaded a few programs on it iobits software suite, all of the windows updates, malwarebytes, free file viewer and file type assistant, google chrome, and apache open office. Was going to finish it off with bitdefender free antivirus but when I run the download, I get the error message "Some installation files are corrupt. Please download a fresh copy and retry the installation." I've tried running the bitdefender uninstaller and have downloaded through all of the mirrors as well and I cannot get it to work. I have these programs installed on 7 other computers (xp 32bit, windows 7 32 bit, and windows 7 64bit), and the download worked just fine. This computer is a windows 7 64 bit.
