I did a manual install with the latest stable release (i.e. -2.0.0.001). I captured the following three screens as I stepped through process:
- Package Center
- Manual Install
- Confirm Settings
I did not encounter any error messages. After rebooting the Synology box (DS1513+ running DSM 6.1-15047 Update 1), openHAB2 was nowhere to be seen. Any suggestions on how to step through the manual installation again with a view to providing more detailed information for troubleshooting purposes? I have read some of the threads for Beginners but I did not encounter those situations. 
Thanks.
