OpenVPN keeps pointing to old location

[Weasel 16]

HI all;  I installed OpenVPN to my D drive, but when I wanted to try running the batch files in this article "Blocking non-VPN traffic with Windows Firewall"  I noticed it pointed to OpenVPN on the C drive.  I unistalled and installed OV on my C and tried to run it but it keeps looking to the D drive.  I checked for any left overs, ran CCleaner for the registry and history, restarted my CPU and installed several times more, each time following the same steps but OV keeps looking for itself in the D drive.  I have tried running both the shortcut and the file itself in programs/openvpn but no joy.

 

It says "create process failed, exe D\utility\openvpn.bin\openvpn.exe" with more stuff below that.

 

Any idea how to point it at the right location?
