Hello, Bucky Brown. Sorry to hear of the problem you are having.
The error message probably indicates that your download of the SudokuSetup file from
the Download page was not complete. Perhaps there was a transmission glitch, or perhaps your ISP (Internet Service Provider) caps the size of files you can download, or perhaps your file got corrupted somehow.
Anyway, could you check the length of your SudokuSetup file? It should be somewhere in the range 1.96 MB to 2.04 MB (the exact size depends on the date on which you originally downloaded it).
You should try downloading the SudokuSetup file again, but before doing so, you need to wipe your computer clean of all traces of past downloads.
In the Error message, there is a reference to a "{FB505~1" directory. The full name of that directory (on your computer, anyway) is "C:\Program Files\Common Files\MimarSinan\Installation Information\{FB5055E4-9BE1-425F-B40A-33E43E9460DA}".
Please delete the entire "{FB5055E4-9BE1-425F-B40A-33E43E9460DA}" directory and all of its contents. You will then have a clean slate. Then you can try downloading the SudokuSetup file again.
Please send me a direct email (using the email button below) to let me know how you get on and/or if there are any problems arising.
