I cant install it

there's a win 10 update bug (or incorrect setting) causing a lot of "no internet connection" errors while there is an active internet connection. see if it applies to you. https://lifehacker.com/how-to-fix-windows-10s-latest-no-internet-connection-bu-1844458254 https://answers.microsoft.com/en-us/windows/forum/windows_10-networking/windows-10-says-i-have-no-internet-connection-but/50153e5b-a008-443d-af0e-5ee3822c37a1

if that's not the issue, confirm that you can connect to the secure adobe servers by reading, http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html

do you see both logos?

if you can and still see a connection error, white list the adobe network endpoints, https://helpx.adobe.com/enterprise/kb/network-endpoints.html
