Yes, but do you use winrar or 7-zip to extract files from archives? As Eagle said you can check the archive for errors/file integrity (with winrar anyway) in case it downloaded incorrectly. With 7-zip you can only compare checksums with someone else. You should try that so that you know the archive you downloaded didn't somehow corrupt or something during the download.
Another thing to consider is whether the game files are blocked, like this example:
You must be registered to see the links
That can sometimes cause errors. I use powershell to remove the blocked file status from directories of files as used in these instructions:
No idea if read-only might cause errors like that too. If you're testing this you'll probably want to rename the files back.
I was originally thinking maybe you had a non-english environement on your OS and you should use
You must be registered to see the links
but that doesn't seem to be the case.
