Okay I think I have figured it out.
First of all, this download is corrupted. In other words, I would choose a more reliable site to download the exe file.
Secondly, the reason you cannot reinstall this perfectly on your computer is because even if it is an invalid application, it leaves entries in your registry. So, once the file is thought to be reinstalled, the corrupted registry entries from the last version still exist.
So, first you should unistall this application. Then, get a registry cleaner program (many freeware ones exist) to clean out the reg entries and then I would redownload the file and try installing it again.
This is just a suggestion. I hope this helps. Aside from this I can only say that your operating system is not perfectly compatible with the file. And even though your system is way over the requirements for the application, certain files maybe required that must be added to run some applications.
