Today, my vs2017 Community Edition has been evaluated. I think it’s OK to log in to my account. However, when I click Check the updated license after successful login, it will prompt “unable to download the license, please check your network connection or proxy settings”.
Check it on the Internet, and you can find the file in the directory C: program files (x86), Microsoft Visual Studio, 2017, community, common7, IDE DDConfigCA.exe (The program path is determined by your own installation. If you can’t find it, search it globally.), using an administrator to run the program.
If not, reopen vs and click Help > register product > check for updated license.
