P.S.

Sorry, I downloaded the x64 version, as you can see from the command prompt.
I had this problem on 64-bit Windows 7. I was running the EventStore as a service. I “fixed” it by deleting the events/event-logs folders.
Huh, I deleted the whole folder, unzipped and ran again with just the --db flag. The system projections were disabled, so I enabled them and they ran fine. I might have screwed up the logs when I was trying to start it earlier with various command-line options. Anyway, it’s working now. Thanks.
