By default, Helix QAC supports Visual Studio 2015 - 2022.
If you need to run Helix QAC with Visual Studio 2017 with update one (or the base 2017 installation), then the Microsoft vswhere utility has to be installed manually by creating the Visual Studio Installation directory if required, and then copying the utility from the installation directory into this Visual Studio Installation directory.
>MKDIR "%ProgramFiles(x86)%\Microsoft Visual Studio\Installer"
COPY C:\Perforce\Helix-QAC-2019.1\components\sync\msbuild\vswhere.exe"%ProgramFiles(x86)%\Microsoft Visual Studio\Installer"These operations must be performed with Administrator permissions. Update two or above of Visual Studio 2017 come with this utility pre-installed so this step is not needed for most 2017 installations.
