I was tripped up for as minute as well. It states it in that article, I had to read it like 3 times because I thought just extracting it was key.
After you unpack it in that directory, then you have to find the "deploy.rar" file. In my case it was hising in C:\ProgramData\Application Data\VMware\VMware vCenter Converter Standalone\sysprep\svr2003\SP2QFE.
But you will only find it after you extract the main files. Then take what's in "deploy.rar" and extract that in C:\ProgramData\Application Data\VMware\VMware vCenter Converter Standalone\sysprep\svr2003 as well.
Like it would have killed them to have that already unpacked ???
Anyway..... After that it took off
