I have upgraded two PC´s W8.1. One is a 64 bit version and one is a 32 bit version. The 32 bit system is not working at all (but all older CCL versions worked perfectly) for the scanning process but freeze the program completely. I have tried several times to reinstall the system without any change in behavior. The 64 bit system showed the same tendencies but after some initial struggles it suddenly start working. It seems to me that the 32 bit version has some bug problem or what??? PC SW F-secure, IE 8, Chrome,
