I searched the forum, but did not see a reference to my problem. Will Designer Pro Version 18 run on Windows 7? I installed it on my aging HP laptop (I'm licensed for 2 copies), but when I tried to authenticate it, an error report said unable to connect to Internet. Error code 12157. I looked that up, and the suggestion was to ensure that my Internet connection was configured for TLS 1.2. It is.
Any ideas?
