The HME files (HyperSizer Methods and Equations) are uploaded on your machine during install. Usually they are saved to C:/HyperSizer Data, however if you install the software and specify another drive to put your HyperSizer Data directory on you will need to tell the software where to look. Under Preferences/Options specify the Document Reference Root Folder as the directory where your HMEs are saved.
Then select “Rebuild Reference Documents Index” to allow HyperFinder to build the directory of documents.
