Hi -
I just bumped into this myself. Uninstalled my old VS2015 and 2017RC installations, NCrunch (on the Core beta) and Resharper - as well as some other related installers. Iinstalled VS 2017 Community, then Pro (wow how fast!). Resharper had options for both; NCrunch installed into Community only.
I followed instructions on
https://www.ncrunch.net/...stallation-instructions for my Pro and that sorted it out. One thing was to use an admin command prompt - I tried running in normal to be able to report here if it didn't work; got an error - when in admin prompt it ran silent and all was well.
