I had a quick bing search and found that I need to install the VS C++ Redistributable of 2015 https://www.microsoft.com/en-us/download/details.aspx?id=48145 to fix the missing DLLs issue.

Thanks for reporting this. In the latest version, users will be suggested to install VS C++ Redistributable if import fails. Let's see if everybody can resolve this issue on their own from now on.
