AMO 4 and SDO 4 do not support Vista which is a much more recent OS.
I am not sure if the version 11.x are still available. So, you will need to upgrade to Client Automation 12.5 x or 12.8 x to obtain the support for recent Operating Systems.
I hope this helps,
Also note there is no upgrade option from v4.x to any of the supported versions.
You would need to install a new system
Do you need further help with this discussion?
Thanks in advance for keeping us posted on its status.
Enjoy your weekend,
