Install free pro and service pack 2 problem

Any suggestions as to what is happening with install of freeware Pro firewall and SP2. Error message upon installation states installation cannot continue without SP2. My SP2 is alive and well, presently residing in network places on desktop. Does SP2 need to be in a different desktop folder for Comodo to find it? I cannot find any info on this on any of the forums…any suggestions would be greatly appreciated.
All the best,

Hi & welcome.

The info you provide is a bit vague to me. Which version of Comodo Firewall Pro do you mean? 3.0 or 2.4? And I suppose “SP2” addresses Windows XP? - you cannot chose where to put SP2, its installation is automatically put in the Windows folder by Windows.
