I am currenlty trying to find out how to get the runnig ArcGIS version.
I found something similar in How to know ArcGis version in C# but it does not answer my question.
When i call RuntimeManager.ActiveRuntime.Version it tells me 10.2. The the versions from "InstalledRuntimes" all returns me 10.2.
But my installed version is 10.2.1. In ArcGIS Administrator i even see 10.2.1.3497. We need to see at least, wether the client machine has 10.2 or 10.2.1 installed. Where to I get the real version number from?
