Uninstall Appium 1.4.16.1 error

Hello,

I currently have Appium 1.4.16.1 installed on Windows 7 32-bit machines and 64-bit machines. Whether I try to uninstall via control panel or silently via command line I get an error. The uninstall completes but it leaves a popup Window from Appium that says an error occurred and to hit close. Once I hit close the uninstall completes.

I have added some scree

nshots of the error but it seems to be in relation to the kernelbase.dll.
Has anyone ever seen this before or have any ideas how to resolve? We would really like to do these uninstalls silently because we have thousands of machines that need this removed.
