I have installed A12 tools - 2022.02 for my Windows computer.
But the Data Modeler tool is not available after installation.
Does anyone know why?

Hi, I think it is because Data Modeller has been retired in 2022.02. You shall use SME for document modelling instead.
For more information about data modelling in the SME, you can have a look at this in the documentation.
Thank you @denise-narrow-token @josef-brisk-cache
