Does not work with Windows' "Mapped network drives"

• Etcher version: 1.4.3
• Operating system and architecture: Windows 10 Pro x64 (VMware)
• Image flashed: 2018-04-18-raspbian-stretch.img
• Do you see any meaningful error information in the DevTools? Yes, an ENOENT error suggesting that node could not open the file. Though I was able to browse to it. Note that it works when the path is specified as \\my-server\share\path\to\file instead of X:\path\to\file with X: mapped to \\my-server\share

I was able to solve this on windows 10 (version 1803) by adding the EnableLinkedConnections registry entry as described here:

https://support.microsoft.com/en-us/help/3035277/mapped-drives-are-not-available-from-an-elevated-prompt-when-uac-is-co

I didn’t attempt either method 1 or 2 from the “workaround” section. Initially, I attempted to change the permissions of the shared folder on my Synology volume to allow all guest/default & domain-user accounts read-only access, but that didn’t seem to make a difference.

@thundron I have not taken the time to investigate the problem any further. I just copy the image to a local disk first now.
