Could you follow these steps?
1) Check the properties of the installer or download
HashTab.
2) Go to properties and check if the size of the file in bytes is 673,571,746. Or if you want to use HashTab check on properties->file hashes and check if the md5 is 7114F2D4C87016F49BAD8F2B37473795.
3) If your installer information is different than the one on step two you need to download the installer again.
If that isn't the problem, the only thing i could think is that you are using cracked CoH or Relic patches messed up the files. If it's the latter, reinstall CoH should do the trick; if it's the former i don't know what to suggest besides "buy an original copy"
