What

Windows sandbox install failures are classified from typed error codes rather than by matching stderr text, and the reported timeout is longer.

Details
  • Codes matched are install_timeout and install_config_conflict.
  • The timeout message now says 2 minutes instead of 60 seconds.
  • Windows-only, on the /sandbox install path.
Evidence

The install timed out after 2 minutes

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
