Anybody knows how the classic client knows who called it and throws that message?
I'am building a router application which should determine which executable should run the link (When try to open a report in rtc which has no layout => opens classic client).
This router then checks based on the connection settings in the link, which finsql version (SP1 or R2) it should open.

When i try to call the correct executable by Prcess.Start(), i receive the above error. So somehow the classic client knows who called him. Based on my research on the internet there is now concept of knowing the calling process of a process/executable so i'am a bit lost. How does he know?

BTW: I'am just interested in the concept, i don't depend on working around this check, i have another workaround without the need to call the classic client myself. but that would involve changing the registry on every start of an rtc client but thats not as clean as i'd wish.
