Problems with installer

Comodo Internet Security - CIS Install / Setup / Configuration Help - CIS

I have tried many times and I keep getting the same error. I have of course tried downloaded it again too.
See pictures for error message:

I don’t have any problems with other setup files.

Thanks in advance!

That is strange. Please try reinstalling by following the advice I give in this topic and let me know if that helps. Also, although you already have, please re-download it again before reinstalling again.

Thanks.
