For those with ipc error and no logging.

[Iphinome]

the IPC error and no logging seems to stem from steam not being installed in the C drive which can be fixed by the creator making a path setting instead of what seems to be a built in auto path that I haven't been able to find to change. The only current way to get this fixed is to re-install steam on C drive, which is to much work so i wont be using this until that is (hopefully) implemented. I did trying creating a false path to the IPC log however steam will only write to the one in the actual steam folder, so the log won't show anything at all.

I have my Steam installed on C:/SteamGames/Steam and get the same Directory Not Found error with the help text of editing the config. Inside the Config folder is just the game .json files, and those don't contain any entries for directory paths.

However, I did find a workaround: folder redirection.
Create a Steam folder in your C:\Program Files (x86), then open a command console with admin privileges and enter the command:

mklink /j "C:\Program Files (x86)\Steam\logs" "your\actual\logs\directory\here"

This will create a directory junction, which will redirect everything looking for the default path to your actual path.
The command will create a junction link named "logs" in your fake Steam folder, however mklink cannot create directories itself, hence you need to create the empty Steam folder first.
