create data dir: %w

Error message

create data dir: %w

What it means

schtasksManager.Install (Windows) first ensures cc-connect's data directory exists via os.MkdirAll(DefaultDataDir(), 0755) and wraps any failure as "create data dir: %w". It fires when the directory cannot be created or verified — typically a permission problem, an invalid path, or a non-directory file occupying the path. The wrapped original error (e.g. access is denied) is preserved for diagnosis.

Solutions

1. Check the wrapped cause in the error text (e.g. "Access is denied") and fix that underlying ACL or path problem first
2. Run the install from an interactive account with a real %USERPROFILE%, or pre-create %USERPROFILE%\.cc-connect manually with correct permissions
3. Verify the path is not occupied by a file: `dir %USERPROFILE%` — rename/remove any entry named `.cc-connect` that is a file
4. If USERPROFILE points to a missing drive, correct the environment variable or the profile for the account

Example fix

// before
$ cc-connect daemon install
// error: create data dir: mkdir ...: Access is denied.
// after: pre-create with correct ACL
> mkdir %USERPROFILE%\.cc-connect
> icacls %USERPROFILE%\.cc-connect /grant "%USERNAME%:(OI)(CI)F"
> cc-connect daemon install

dataDir := os.UserHomeDir() + "\\.cc-connect"
if st, err := os.Stat(dataDir); err == nil && !st.IsDir() {
    log.Fatalf("%s exists but is a file; remove or rename it before daemon install", dataDir)
}
if err := os.MkdirAll(dataDir, 0o755); err != nil {
    log.Fatalf("cannot create data dir %s: %v — fix ACLs/profile before install", dataDir, err)
}

if err := daemon.Install(cfg); err != nil {
    var pe *fs.PathError
    if errors.As(err, &pe) && strings.Contains(err.Error(), "create data dir") {
        return fmt.Errorf("check permissions/ACLs on %s and that USERPROFILE is valid: %w", pe.Path, err)
    }
    return err
}

When it happens

Trigger: Running `cc-connect daemon install` on Windows when the default data dir (under %USERPROFILE%\.cc-connect) cannot be MkdirAll'd: read-only or redirected USERPROFILE, antivirus/ACL denial, or DefaultDataDir() resolving to a drive letter that does not exist.

Common situations: Installing as a service account whose profile is not provisioned (TEMP-profile services); roaming profiles with deny ACLs; running from a sandboxed/readonly environment; a stale file named `.cc-connect` sitting in the profile root.
