What it means here

Windows rejected a malformed path, URI-like value, drive specification, or name.

What to check next

1. Inspect the expanded value for illegal characters, quoting, and doubled separators.
2. Validate UNC paths and drive mappings in the executing account's session.
3. Check whether a deployment tool expects a local path, URL, or OMA-URI instead.
