If you have already extracted the Zeit wallet 1.0.1 version then it should have all the .DLL files in it, all I did was extract the v1.0.2 zip in to the folder where the 1.0.1 filer were and it worked fine.

If you don't have it then throw 7zip on to your machine, you can double click on archives and specify which files you want to extract.

The new option to unlock wallet for minting is pretty sweet
