RC 17 , 32-bit version closing

I installed it anew via download from directly from your site, but this didn’t help either: It stillcloses after some seconds.

Does it crash if you trigger Help > Check for updates? Does it still crash after you disable automatic updates in the File > Options?

Please, attach a log file too.

Where do I find the log file?

to answer your question:Scrivener just closes itself after soem seconds. Before I can do anything like checking for updates or whatever…
there is no time to disable anything.

Disconnect from the Internet and disable Auto Update in the File > Options.
The log file can be generated via running ScrivenerLog.bat as administrator. The log files are generated within the “logs” subfolder of the Scrivener installation.
