"File not found" error when deploying to Windows Phone 8

Question

I'm trying to deploy my first Windows Phone 8 app to my brand new Lumia 920, after getting everything up and running on the emulator, but I'm running into the following error during deployment:

1>------ Deploy started: Project: AudioFilteringPhone, Configuration: Debug ARM ------
1>Deploying C:\Users\<username>\Documents\Visual Studio 2012\Projects\AudioFiltering\AudioFiltering\Bin\ARM\Debug\AudioFiltering_Debug_ARM.xap...
1>Connecting to Device...
1>Optimizing for device...
1>Installing the application...
1>Deployment of application to device failed.
1>Error writing file '%FOLDERID_SharedData%\PhoneTools\11.0\Install\{29b31259-9af9-47a5-9891-c3098315d3d8}\AudioFiltering_Debug_ARM.xap'. Error 0x80070003: The system cannot find the path specified.

If I manually try to deploy using the Deployment tool, I get the same error. Does anyone know what the cause of this is and how to alleviate it? This happens even if I just start a new WP8 app and immediately try to deploy it, so it's something wrong with my environment, not my application configuration.

Answer 1

I had exactly the same problem, but solved it by simply rebooting the phone. No software updates were required.

Answer 2

It turns out that there were software updates that needed to be installed. If anyone knows a way to find out the names of the updates applied, I will post them here, otherwise all I can say is that I had to update to OS version 8.0.10211.204.
