Some of you may have experienced file write errors or several errors when Kokua starts the auto update windows installer. This problem is intermittent. I’m thinking it is a timing issue with writing binary files from the installer. I found that the Retry button in the error message box can be used to obtain a complete install. It may take several Retries to get the installer to complete. Below linked are two Second Life jira issues that document the problem.
