LabVIEW Installation

Hello ,
Team 2420 was given a corrupt LabVIEW software installaion drive. We fixed it; no problem. The main issue , is that our classmate’s (C:) drive is full. Every attempt to clear it results in a window saying"You require permission from TrustedInstaller to make changes to this folder." The contents of this drive WILL NOT delete. How much space is needed to install the LabVIEW software? My question is regarding the uninstallation of these folders. Please help!!

LabVIEW needs about 4GB of space.

On a 2010 Classmate (E09) we were able to reimage it with the 2012 restore stick, and had space to install LabVIEW, Utilities, Driver Station, Kinect Server. Leaving about 1.23GB free, which is enough for a LabVIEW project.

Are you using the Windows uninstall tool (Control Panel -> Programs and Features) to remove stuff or just trying to delete system folders?
