Cnet makes a list of software available for download through Cnet Downloads (formerly download.com), but does not actually sell any of the software. All transactions are between the purchaser and the respective developer and/or eCommerce store. Thus, unless the executable is offered on download.com, you will have to contact the company you purchased the software from.
Hope this helps,

Hi, I just recently today purchased the premium version of the AntiVira product. I am running with XP Home edtion. The download commenced and got to the stage where it needed to uninstall the previous older version but, seemed to be taking too long to complete the job. After 2 hours of nothing but still removing the odler version, I decided to turn off my PC.
Question is, how do I get to complete the upgrade of the full premium version, where do I fing the exe file to re start the download?
Regards
