In some cases there is a possibility that the system is not able to retrieve the domain information, in this case the T1C is not usable. To solve this problem you can follow these steps described here; https://www.hostinger.com/tutorials/fix-dns_probe_finished_nxdomain
When installing the T1C the possibility of the errors 2502 or 2503 originate from the fact that permissions in the temp folder (C:\Windows\Temp) are not correct, and since the MSI installer relies on this they need to be correct. You need to have permissions next to the administrator rights.
You need to have permissions as <My User> next to the administrator rights.
