This error indicates that the screen capture codec was not installed in your computer. In some rare instances this may be the result of very restrictive security software not allowing activeX components in your system. However this problem can also occur on some custom Windows installation (especially Windows 7). Make sure the file regsvr32 located in the folder C:\Windows\SysWOW64 and the regsvr32 file located in C:\Windows\System32 have the same version.
