but inside my windows 10 PC, i installed the sharepoint designer 64-bit from this link @ https://www.microsoft.com/en-us/download/details.aspx?id=35491, and after that i checked the version for the SP designer, which was lower than the previous version. the new version is
15.0.4420.1017, as follow:-
So i am not sure how i can upgrade my SP designer version inside windows 10? the issue is that inside the above download link they mentioned the following:-
Please make sure your installation of SharePoint Designer is up to date by using Microsoft Update, or installing Service Pack 1 from here
but inside the Service Pack 1 download link the supported operating systems do not include windows 10. So i am not sure how i can get the latest version for the SP designer inside windows 10?
