The first time I opened Studio it first installed NodeJS (failed during install:
TISTUD-7964) and then hanged at Configuring for a loooong time. Finally, it failed with:
Which is weird, because when I opened PowerShell and did appc it installed the latest core (5.1.0) fine. When I opened Studio again after that it was all OK again.
How can Studio fail where CLI succeeds?
See the attached log file from Studio.
