This tool was previously a part of the old OHDOTCEv02_AdminTools_Installer. It has been separated from the installer to its own application. also note that the installer was renamed from OHDOTCEv02_AdminTools_Installer to OHDOTCEv02_WorkSpaceTools_Installer.
After running the installer, the 2nd step is to launch the OHDOTCEv02_WorkSpaceSetup_Tool from the start menu. this application is used to define/setup as many OHDOTCEv02 workspace instances as desired (Local, network, ProjectWise Explorer)
There is also documentation, which can be found at the link below. Please note this document is not a walkthrough guide, it is to document the available options and what they do/mean within the application.
