I have an application that’s running 24/7 without attendance. It’s deployed via ClickOnce and needs to check and download updates by itself. It checks for updates at application startup and at scheduled time at night. When it does it on startup, it works perfectly fine.
However, when it does it at scheduled time, it crashes. In both cases it’s using exactly the same piece of code. It’s running under Windows 7 and might have something to do with UAC. I’m thinking that maybe it cannot access file system when computer is at idle state? I really need to fix that. Here are the exception details:
Message:

configuration and the account configuration. (Exception from HRESULT:

EDIT: I think the cause might be that the hard disk drive is turning off after some time of the system being idle. Is there a way to programatically turn on the hard disk drive before I check for updates (using C#)?
I will put this link here just for the record: link to MSDN forum. According to it, it’s a bug in ClickOnce internals which causes this error to appear after certain number of calls to the CheckForDetailedUpdate() function.
