Hi Don,
there is some known issues with antivirus interference but as long as antivirus is enabled when installing, you should be ok.
Can you please provide a bit of detail? what do you mean "ccs does not work" and that you can not download ccs?
i would download and try again in a clean directory with antivirus off. Please keep us informed and send any install logs (should this not correct things). The logs are in the installjammer registry folder which may be hidden and is under program files or program files(x86).
Best Regards,
Lisa
