That is a very old version and a no longer maintained release. Please 
*uninstall* it, and then install WinAVR.

That's because you are trying to convert it to a different file type 
that is no longer supported. Again, *uninstall* the previous release 
first, then install WinAVR. Read the README file that is included with 
WinAVR.

To get a new project going, use the sample Makefile template that is 
included with WinAVR, and modify it according to your project needs. 
Alternatively, you can use MFile that is included with WinAVR to 
generate a Makefile for your project based on input that you provide. 
The Makefile template that MFile uses, is the same template that is 
included as the sample Makefile in WinAVR.

For a tutorial, see the WinAVR web site:
