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. Do not edit the script. Do not change protection settings, install\nsoftware 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, failed cleanup or a script error that cannot be fixed\nwithout changing the file. Preserve each original error.\n\nReport the actual attempts, approvals, errors and final status. Reply in English.\n",
