The project contains file with name "generation.vsconfig" in a inputs folder. It looks like it was created correctly respecting all constraints. But import section doesn't work for me. I tried to create my own .vsconfig files then invoking StandaloneScriptExecutor.executeScript(path) method gives the same error

One of the possible solution may be to provide built version of VIATRA-generator. (According to wiki Installation Guide the only way to install this plugin is to build from source code). The user's environment may differ from the developer's and this may cause problems

I would like to ask you to provide more details on launching your model generator
