Does this happen with a clean install of mIRC? Are you able to reproduce the issue using a specific set of steps? Listing error results from procmon is not that helpful I am afraid - it is quite normal for events to return error values, "name not found" values or other combinations of succesful or not succesful results from calls to functions. Also note that mIRC has no idea what "HKLM\SOFTWARE\Microsoft\CTF\KnownClasses" is and does not access that registry key itself, so it is likely that one the system DLLs is doing so on behalf of mIRC. mIRC, like all other applications, uses system DLLs which perform all kinds of functions that mIRC has no control over.
