it turns out OK. If it does you'll know where the problem is. If not then try and reinstall the installer. Are you using bit torrent by chance? Others are availalbe from downloads.com.
Lots of things I try to download come up corrupt. They will download 100% with no interruptions but when I try to install it says the installer is corrupt. I'm only running an AVG Free A/V program and windows firewall. I reformatted my computer recently hoping to fix this because it started happening before, so windows is fresh, 2 days, and I havent been connected to the internet much and no downloading off of unrespected sites. The download worked on a different computer and then I transfered the file through aim to this PC and it was corrupt. Any solutions? I remember when I first got this computer I had an nvidia firewall installed and changing an activearmor setting fixed this, but I avoided installing the firewall this time in attempt to avoid having to do such, but that didnt work. Some downloads will work with the /NCRC command, but some dont.
