DISM fails with 0x80070020 when trying to flash Windows 10 IoT to an SD card

I'm trying to flash Windows 10 IoT Core to an SD card through the IoT dashboard, and not having much success. The image downloads correctly, and the installer unpacks, but once the flashing begins DISM gives me the cryptic error Failed to create a new block flasher object., accompanied with the error code 0x80070020. This appears to normally indicate that the files are already in use, which confuses me given that there are no files present on the SD. Removing and replacing the card has made no difference so far.

The full DISM log is below:

Does anyone have any ideas as to how this can be resolved?

Thanks all!

EDIT: Jeremiah Johnson on MSDN suggested that I update my computer to the same version of Windows as the one I'm trying to flash to the card, which I did, and I now get a slightly different error:

Any ideas?
