The download for the Chilkat x64 ActiveX components includes a register.bat batch file for registering each of the Chilkat ActiveX DLLs.  If some or all of these fail with an error code of 0x80070005, it is because of a permissions problem.  Do the following to successfully register the ActiveX DLL’s on the system:

  1. Copy the DLL’s to c:\Windows\System32
  2. Right-click on the “register.bat” file and select “Run as administrator”.
  3. The DLL’s should register.
