@Torquinox - Well my instructions were based on the information that the original poster shared -

INSTALLATIONS INSTRUCTIONS

Unzip the "PROHIBITION POLICE CAR BUNDLE" folder in your My DAZ 3D Library folder.

If you don't have such folder, create it in Users/Public/Documents/

The FORD B 400 POLICE and the LINCOLN 1929 POLICE are now located in Props/3DClassicsVEHICLES/

I do not install my stuff this way at all. I was only assisting him with how to get the information to work if he followed the instructions he shared above. I have absolutely nothing install in Users/Public/Documents.

Did you even read what he posted. My response was to help with the information he shared. I do not have one large runtime as many here have. I have runtimes based on

Themes.  Example my Prohibition Runtime includes all clothing, props, etc that pertain to that time period such as flapper dresses, hats, jewelry, shoes, tommy guns, gangster stuff, and anything else from that time period
