Always get corrupted file notice when downloading games

[stic]

Whenever I try to download any game (besides Minecraft), the download completes fine. I open it up, and one of three things happens:

1: I get this message: Error: The setup files are corrupted. Please obtain a new copy of the program.

2: I open it, the installer comes up and installs 99%, and I get a similar message, only this one has to do with a specific file.

3: I open it and get an NSIS error that goes like this: Installer integrity check has failed. Common causes include incomplete download and damages media. Contact the installer's author to obtain a new copy. More information at http://nsis.sf.net/NSIS_Error

I followed the URL, did as it said, to no avail. My computer or something Windows-overprotective-ish is most likely to blame, due to many other people downloading these games seamlessly. I have a Toshiba C55D-A with Windows 8 64-bit, 4GB RAM, and an AMD E1-1200 APU Radeon.

most programs don't check for file corruption. if they did you would be shocked at how common it is. the most likely cause of file corruption that you can fix will be caused by your network driver for your network card. if you download a file and it is corrupted, rename the file to file.bad and get another copy then do a file compare of the two files. if they are the same then update your network device driver to a current version and get another copy and see if it is corrupt. if it is not then the old device driver assembled the packets incorrectly and caused the corruption. this is the easies corruption to find and fix, others can be cause by any component that the file is translated by. cable modem, router, local machine tcp/ip stack, network driver, clear down to the bugs in the hard drive you store the data on.

(this assumes you checked for likely corruption caused by viruses)
