So I've been using ThemeKit to build a Shopify theme and I've been getting a notification in the command-line window that ThemeKit has an upgrade available. It says to use theme update as the command to run to get this done but when I do I get this error message, Could not update and had to roll back. open C:\Program Files\Theme Kit\.theme.exe.new: Access is denied. Anyone else have this issue? I'm working on Windows 10 if that helps...
