If you havent already:

Install the latest Poser SR !!!

Redownload and install the latest version of the DSON-importer !!!

Redownload and install the latest version of the Genesis Starter essentials  !!!

 

DSON importer goes into the Python script folder of your Poser installation.

Starter Essentials (and Genesis clothing) go into a separate runtime you link to Poser.

Same with companion files.

Starter essentials and Genesis stuff usually unzip to a folder named "content". Copy/paste everything inside that folder into your "Genesis" runtime linked to Poser
