- Press key combination Windows + R
- Type cmd.exe
and press Enter
- Change directory to the directory where your installer was saved. I guess in your case it is Downloads directory. So. you need type cd Downloads
then
- Start the installer via command line with enabled verbosity and redirect log output into the text file for convenience: OVPN.exe -v > install_log.txt
- Perform the installation till your error. Quit the installer's UI and check out the output in the log file installer_log.txt
. The log file should be created in the same directory as installer directory. Installation log file should contain detailed information about the install process. Your error might be highlighted in the file.
