In your Release Notes PDF /cfs-file/__key/communityserver-discussions-components-files/5930/LBC-CE-V19-M1-Release-Notes.pdf you have the following...
Directory Structure
The default directory of LEAP Bridge Concrete is "C:\Program Files\Bentley\LEAP Bridge Concrete \", if the
user has not changed the location during installation. The tutorials are installed in the Example directory
within LEAP Bridge folder. Help directory within LEAP bridge folder contains all the necessary help files for
individual components. Lib folder contains the default library files for rebars, tendons, cross sections. It is
recommended not to delete the default library files. Starting with v12.01.00.57, there is a change in the
location of the library files. During installation, program libraries will by default be added under
“C:\ProgramData\Bentley\LEAP Bridge Concrete\” folder to comply with Windows standards to eliminate
problems with access to users without Admin privileges. If you have customized program libraries, you
can move them to the above folder, and set the correct paths in the Library Setup dialog from within LEAP
Bridge interface.
This is incorrect. The default path in the installer for LEAP Concrete is "C:\Program Files\Bentley\LEAP Bridge Concrete CE V19" and "C:\ProgramData\Bentley\LEAP Bridge Concrete CE V19"
These default paths by your installer break OpenBridge Modeler interoperability.
This issue will be reported to the development team.
Thank you for looking into this issue.
