The most likely cause is a region mismatch between the Microsoft account, billing details, or purchase region rather than the Windows region alone.
Try these checks in order:
- Verify the Microsoft account country/region
- Go to the Your info page of the Microsoft account dashboard.
- Select Edit profile info.
- Confirm that Country or region is set to Argentina.
- Check payment details
- Open the Payment options page.
- Confirm the card details and billing country match Argentina.
- Remove outdated or incorrect payment methods if present, then add the card again with the correct billing information.
- Check for account issues that block region changes or purchases
- Review the Services page for any overdue subscription payments.
- Check whether the account is temporarily suspended.
- If an Xbox account suspension exists, that can also block purchases.
- Confirm the account has not changed region recently
- If the country or region was changed within the last three months, that can prevent another region change.
- Spend any Microsoft account balance before changing region
- Microsoft account funds do not move between regions.
- Update Microsoft Store or device if prompted
- If any purchase flow shows “Unable to complete this transaction. Please update to the latest version of Microsoft Store”, update the Microsoft Store app from Library > Get updates.
- Reset Microsoft Store on Windows
- Press Windows key + R.
- Enter wsreset.exe and select OK.
- Wait for the Store to reopen, then try the purchase again.
- If the issue continues, contact Microsoft Support
- For account-specific regional or billing configuration issues, use Contact Microsoft Support.
- For purchasing issues, Sales support is also listed as the support path.
Important points:
- Changing the Windows region alone may not resolve purchase-region errors.
- Items and services obtained in one region might not work in another.
- If the account region, card billing country, and purchase region do not match, purchases can fail.
