It happened to one of my friend today. He was trying to add a class in an MFC application and got stuck when an error message came out. This error is caused by a change in the security policies of Internet Explorer 8 and is documented by a blogger on MSDN (click on title for original post).
- Open regedit (on a 64-bit OS, open the 32-bit regedit)
- Under “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones”, create a new key called 1000 (if it isn't already there)
- Under 1000, create a DWORD entry with:
- Name = 1207
- Type = REG_DWORD
- Data = 0x000000
