The XP I'm loading the pro/E into has had SP2 added. This service pack creates a new and improved Security Center, which will not let ptcsetup.exe finish as long as the Firewall is On. I set the Firewall to Off at the General tab and did the installs. Then went back and turned the Firewall back on. Got a Firewall acceptance request box for java at the Ilink start; comm_msg and xtop at linked ProE start. Everything seems to work o.k.
Please advise if it has been found more is required. thanks
