Arduino Zero compiler access denied (Windows 7)

I've recently installed the Arduino IDE on a Windows 7 machine and have been encountering the following problem when compiling for my Arduino Zero with this setup:

fork/exec C:\Users\shane.lillie\AppData\Local\Arduino15\packages\arduino\tools\arm-none-eabi-gcc\4.8.3-2014q1/bin/arm-none-eabi-gcc.exe: Access is denied.

I've tried reinstalling the Arduino IDE, the Arduino Zero board tools, and the libraries I've been using but none of that seems to fix the problem. It works fine on a different machine (using Windows 10) so it seems like it's something with this particular installation, but I can't for the life of me figure out what it would be. This is the full output from the command that seems to be the problem:

I figured maybe changing my environment TEMP/TMP directories to C:\Temp would fix it, but it did not. I'm not sure what else there is I can do here.

I think I solved a similar problem on my Win7Pro machine by changing the Permissions access/properties on the folders that were being denied.

I'm not sure what exactly is being denied here. Is it the fork/exec call can't access the compiler? Or is it that the compiler can't access the temp files that the IDE created? Nothing changes if I run as administrator so at the end of the day I don't know what permissions exactly to fix, if that's what needs to be done.
