hi DeviHan,
1. in debugger menu "component", "set connection". choose "HC12" and "Full chip simulation".
2. then in debugger menu "HCS12X FCS", "set derivative". seclect the right chip you need work with.
3. then in debugger menu "file", "save configuration"
relaunch debugger. see how it works.
if problem still exists, please restart your computer and reinstall your CW to another disk.. for example : disk D
make sure you have admin right when install and use it
