Can't install chocolately when the zip shell extensions are disabled

[tmyroadctfig]

I've killed off the default zip shell support in my copy of Windows 7 because I find it annoying and slow compared to 7zip. Unfortunately it seems to have killed the chocolately install along with it:

Ensuring chocolatey commands are on the path

It seems quite similar to #59

This also seems to break installing new packages. I think I initially killed off the zip integration via:

regsvr32 /u zipfldr.dll

and now that I've restored it running:

cmd /c assoc .zip=CompressedFolder

everything seems to be working again.
