Commented Unassigned: System.InvalidOperationException: Compiling less caused a scripting host error. [1832]

Hello,

I receive the error detailed below when running Composite C1 on my Windows 2012 x64 Server. I installed via the web platform installer, and dont appear to have any sort of theme because of this error.

I have tried uninstalling and reinstalling the Composite.Web.Css.Less package, after another user had an error with this same package (just a few days ago). This has not resolved the issue. I restarted IIS for this site afterwards just to make doubly sure.

If you email me (mark@ascended.com.au) I'd be happy to provide the website and console login details available as this is a test install.

Server Error in '/' Application.

Hello,

Yes, it is running version 1.2.1. I found over here: https://github.com/joyent/node/issues/3977

That it is a permissions issue. I'm running Plesk on this server to make life easier, however it restricts access to the IIS users to anything other than their web directory.

I added permission to "Everyone" for the C:\ directory ("this directory only"), as well as program files. This allowed it to look in these locations for node.exe and figure out it's not there.
