create log dir: %w

Error message

create log dir: %w

What it means

In schtasksManager.Install (daemon/windows.go), after creating the data dir the manager creates the parent directory of the configured log file (os.MkdirAll(filepath.Dir(cfg.LogFile), 0755)); any failure is wrapped as "create log dir: %w". It means the directory that should hold the daemon's log file could not be created, so install aborts before writing the task script.

Solutions

1. Fix the log file path in config.toml so its parent directory exists or can be created on a writable local volume
2. Manually create the directory: `mkdir <parent-of-LogFile>` and grant the account write access (`icacls <dir> /grant ...`)
3. Check the wrapped cause: "Access is denied" → ACL issue; "The system cannot find the path" → bad drive/typo
4. If a file already occupies the directory path, rename or delete it, then rerun install

Example fix

// before (config.toml)
log_file = "E:\\cc-connect\\cc.log"   // E: does not exist
// error: create log dir: mkdir E:\: The system cannot find the path specified.
// after
log_file = "C:\\Users\\me\\.cc-connect\\cc.log"
$ cc-connect daemon install

}

When it happens

Trigger: `cc-connect daemon install` with a Config.LogFile whose parent directory cannot be created — bad drive letter in the configured path, permission denied on the target folder, an existing file where a directory is expected, or a path with illegal characters.

Common situations: Config pointing the log file at D:\logs when D: is a removable/absent drive; log dir on a network share without write access; typo'd config (e.g. log_file = "C:\\log.txt.bak\\cc.log"); running under a service account lacking rights to the configured folder.
