Installation Error Python 2x & 3x .msi packages (Windows7 Ultimate amd64 OS)

... After a reinstall of my OS and basic apps e.g., AV, notepad ++, etc... I downloaded the Python .msi's for 2.7.2 amd64bit and tried to install it. It showed this error:

... After clicking OK the installation is aborted and the changes rolled back. I tried various versions all had either the same error or another error stating that something in the download was corrupted. I generated MD5 hashes for each .msi and checked them with list on the website they all matched. I tried checking for compatibility issues and that resulted in skipping version checks. This also did nothing to fix the problem.
