Are you just looking to set it up with iOS and Windows clients? If the Wireguard server is running Linux, an easy way to copy the config over to an iOS or Android device is to use qrencode. For example, `qrencode -t ansiutf8 < $config_file` will output a QR code that can be scanned from the Wireguard app to automatically import as a new tunnel.

I used StavrosK's guide (thank you!) to put together two scripts a while back, one for generating a new server config file, and one to generate a new client config, outputting the config to a file as well as to a QR code on stdout. You can copy the client.conf file over to the Windows machine and import the configuration via the "Import tunnel(s) from file..." option in the Wireguard client, or scan the QR code output from the mobile device clients via "Create from QR code".

Here's my script for generating a client cert: https://cdn.seedno.de/txt/wireguard-certgen. It assumes Wireguard is already configured on the server on interface wg0, and is using the default port of 51820/UDP, though both are configurable via variables. For reference, the accompanying setup script is https://cdn.seedno.de/txt/wireguard-setup. Both scripts require a bit of customization to match your environment (you may want to be particularly careful with the iptables firewall PostUp/PostDown commands), but hopefully they can serve as a starting point to figure out any issues you encountered last time you tried.
