windows system exec error in application causes app to crash

The basics:

LabView 11.0 (32-bit)

Windows 7 enterprise

Because I have to control an elevated app I run my built app elevated on a Win7 64 machine.

 

I have an application that uses the system exec.vi (attached) to get a portion of the arp table. When I run this in development it works great. However when I build an app and run it this vi causes the app to be unstable and crash.... sometimes. I have a troubleshooting vi that I wrote that I place at the start and end of vis. This puts a log file on my desktop so that I can trace where it crashes. I've attached the log as well.

 

Basically we have a power controller that we control by Telnet but 1st I have to get the IP. I have the MAC of the controller which is DHCP but not the IP. To get the IP I fill the ARP table and search it for the MAC.

 

get ARPCache.vi throws the error messaage: System Exec.vi . Command was "cmd /c "arp -a | find "192.168.120"" but only in the built app.

 

Update: While getting more info to complete this post I did a build where I changed "get ARPCachs.vi" to show when called so I could see the error cluster. Now it pops up but no errors. hmmm
