In my application parse HTML document by using IHTMLDocument2, EOleSysError exception is raised during creating instance of IHTMLDocument2. In few days ago, My application worked correctly. Are there anyone has information about the phenomenon like this ?

My OS is Windows10 (64bit).

  • This answer follow my comment. Maybe Security policy about COM had been changed in KB3206632. I confirmed system log. Event ID 10016 was recorded. So I set appropriate permission by using "regedit.exe" and "dcomcnfg". And finally, My application has work correctly after re-install KB3206632 .
