The ORM Foundation

 After downloading the install package, unzipping, and clicking the setup.bat file, I see this error:

Natural Object-Role Modeling Architect for Visual Studio 2015 Installation

Installing current PLiX version

New PLiX version failed to install

Press any key to continue . . .

I have VStudio 2017 - could that be the problem? 

 Each version of NORMA is specific to the  Visual Studio version so NORMA for VS2015 will not run under VS2017.

 Expounding on this VS2017/VS2019/VS2022 versions of NORMA all install through Visual Studio Marketplace. There is no longer a separate download and traditional msi setup install.

1. Open the Visual Studio Extensions dialog (Tools/Extensions in VS2017, Extensions/Manage Extensions in VS2019 and VS2022).
2. Select the Online section on the left of the dialog
3. Search for NORMA
4. Among the results you'll see Natural ORM Architect and Natural ORM Architect (Per User). Select either package and click More Information for a discussion on the differences. Basically, Per User installs without admin rights and can update automatically, but you need to make an extra click to get IntelliSense help if you ever look at NORMA files in the XML editor. Just pick one package (do not install both).

 Thanks. just what I needed.
