I am installing it to D: and it keeps returning an insufficient disc space message. The install wizard shows available 49gb, required 27mb. I've turned off all virus ware etc..
I used Workspaces for the first time about a fortnight ago for a Hackathon here. I definitely recall doing something in order to install Visual Studio but I can't recall what. It was almost certainly something like changing permissions on Program Files or changing the install path.
Yes, it installs normally.
Make sure you install to D: not C:
You might just need to check permissions to where it's installing.
