I am the author of this tool.
The tool is a very simple autoit code - I do not have any idea why some Antivirus-tools flag everything compiled with Autoit as a virus or trojan.
I attach the source code so that you can compile it yourself - if you like.
If I remember right the version that Andre linked to is outdated - the new one attached also works with Fusion 4 and ESXi 5.
Anyway - extracting the vmx-information from a log file is trivial - it just requires some manual work - see my howto
