This is strange.  I presume this is LabVIEW 2013 installed on a Windows PC, right?  [You don't give us much information].  I'll note that I've never seen a Windows system where the System Device wasn't C:\, and where Program Files (x86) wasn't on the System Device.  Can you confirm this extremely unusual System Configuration?

I still suspect the non-standard location for Program Files is causing this.  Please try the following, which I've pasted as a LabVIEW 2016 Snippet, but have labelled so you should be able to create (most of) it yourself:

Show Defined Paths.png

The key to this routine is the sub-Palette "File Constants" on the File I/O Palette.  If it includes the System Directory function, then code the top loop to return the 14 Named Paths (and their names).  When you run this, look to ensure that all of the Paths make sense on your system, specifically that none of them use C:\Program Files (x86).  On my system, the C:\ drive is definitely represented ...
