Unable to start Blender on Windows

[TomasHubelbauer]

Hi! Thank you for developing this extension, it is exactly what I've been looking for!

I have just installed the extension and attempted to run the Blender: Start command, however, the log in Terminal indicates an error:

> Executing task: c:\Program Files\Blender Foundation\Blender\blender.exe --python c:\Users\TomasHubelbauer\.vscode\extensions\jacqueslucke.blender-development-0.0.12\pythonFiles\launch.py <

I think the solution to this error is included in the error message and I've look at the source a bit, but I am not sure if it is the extension which is attempting to run the pip command or Blender itself or what. I will be glad to send in a PR with a fix, but I'll need little hand-holding, some tips where to look. pythonFiles/launch.py seems like it only launches Blender, so I wouldn't know where to pass --user to Pip there.

I am using Blender 2.80. Both Blender and Pip are in my %PATH%.

Administrator permissions are required to install the dependencies when Blender is located in C:\Program Files.

Thanks! That's exactly the problem I was having!

How come on Windows i get this error while im the Admin? I recently started on windows again after 17yr OSX, need some adaption again. Im the only user with admin rights, not sure i understand why i wont have permissions on this folder?

Edit I just after setting 'Full Control' on Creator and Users part it does seem to work. Still wonder why im not in Admin mode, Windows is really weird and different in that behavior
