Uploading issue

Dear person in charge
I want to use WinSCP 5.21.7 version.
Could you please let me know not be automatically upload WinSCP 6.1 version.

I'm not sure I understand. Do you want to downgrade to 5.21.7? Why? Was WinSCP updated to 6.1 automatically somehow? WinSCP never updates itself. If it did, you must have some (corporate?) solution in place that does it. We have nothing to do with it.
