We have a COM component which registers fine under NT4, Win95. Under Win2000 is says successfully registered, and then Win2000 says regsvr32 has caused an error and a log file is being written. We can't find any log file written and their is no events in the event log? If the component is installed under MTS in win2000, it installs, but no interfaces can be found. Any ideas?
