If execution is restricted,\nrequest the product's supported approval for elevated permissions or execution\noutside the tool sandbox. You may try another installed Python interpreter or\nanother supported launch method, but must run this same file without changing\nits contents. Explain the temporary desktop disruption when requesting approval.\nDo not change protection settings, install software or touch unrelated windows.\n\nUse at most three execution attempts. Spend no more than two minutes on retries\nand waiting for approvals. Continue only after required approval is granted.\nWait for a pending job instead of launching a duplicate. Stop after an explicit\napproval rejection, partial window creation, failed cleanup or a script error\nthat cannot be fixed without changing the file. Preserve each original error.\n\nReport the actual created and destroyed counts, attempts, approvals, errors and\nfinal status. Reply in English.\n",
