I had problems upgrading from 2.6 to 2.7, and decided to go with a clean and new VM (Win10 64). Nothing else has been installed but Win 10 has been updated. The SPT runs and finds no errors or problems. When I try to install a Workstation with open file system, the install starts but never gets past the first line (Dot Net check). A "Setup Failed" message appears and no other errors are noted. Both required versions of Dot Net are available according to Windows Control Panel.
Can I look for clues in the install files? If so, what do I look for? Which install files should I look in?
