According to the documentation the SAS Universal Viewer only takes up 5MB of space. If your main system drive has so little free space I doubt your laptop will be performing well. Try deleting files you don't need and run the Windows Explorer Cleanup Temporary Files function including emptying the Recycle Bin.
The SAS Users Group for Administrators (SUGA) is open to all SAS administrators and architects who install, update, manage or maintain a SAS deployment.
