1. Drop the directory prefix from the liferay.home property. In other words turn this

   liferay.home=C:/Users/Nathan/deployment/liferay-dxp-current

   into this:

   liferay.home=/Users/Nathan/deployment/liferay-dxp-current

1. Startup the portal.
2. Download the latest Liferay Connected Services lpkg (4.0.0) from marketplace.
3. Place the lpkg in the deploy directory. 

Expected:
LPKG deploys normally

Actual:
