Issue/Introduction

 I am receiving error "Aion open error - file open is currently in use by others process" when I am trying to restore a Aion app. What could be causing this error?

 

 

Environment

Release: 9.1 

Resolution

Make sure that when restoring the app, the "read-only" appname.APP file property is unchecked.  Aion could not write/rewrite this file, and therefore threw the error that the file was in use by another process.
