1 path error

 

You have an error in the OpenVPN configuration file.

Open it in a text editor like notepad - it is located somewhere like "C:\Program Files\OpenVPN\config\*.ovpn"

Scroll down to find where you have defined the paths to the client certificate and key, and the server certificate.

 

2 fix paths

 

Double check you have these paths correct. Remember, if you are on a 64bit machine, your certificates will most likely be in "Program Files (x86)" not "Program Files"

Another thing to remember is that windows paths must be absolute (as in starting with a drive letter), and each backslash in the path must be a double back slash.
