Unlike Bob3160 who installed this patch on 2 computers with PCTools FW PLUS and IE8 b2, I wasn't successful. I have exactly the same message error with or without Comodo3 FW (shut down AVAST, PCTools FW and all my other security app.). C-R-U-C-I-F-I-X-I-O-N is the word and yes I cleaned my registry with MV Reg Clean and Glary and Advanced Windows Care. Now Comodo3 FW was filtering too much, on my ISP speed test page (go Videotron, go technical support) I get now 6300 or so kpbs download, double what I got with Comodo3 FW. Just a tear for the rate A given by Matousec to Comodo, if it's worth that. It's not an intelligent FW and when you install its drivers Windows warns you they aren't approved by Microsoft. Oh, yes, I masked the update! :'(
