> Currently, for pre-2017, the root directory must be in the form <some path>/VC.
Note that these development builds (both my actual ones, and the repro constructed from the nuget package) are 2017-class. They just don't conform to 2017's normal installer.
> Could you try renaming x86ret and amd64ret to VC and try it again? e.g.:
> C:\Temp\binaries\x86ret\bin\i386 ==> C:\Temp\binaries\VC\bin\i386
> C:\Temp\binaries\amd64ret\bin\amd64 ==> C:\Temp\binaries\VC\bin\amd64
Sure. x86 still misbehaves, but x64 works properly! Does this indicate that Clang just needs to do slightly less strict validation of the root directory (possibly controlled by an option)?
