Installing the authoring tool on Windows 10 1703 will not allow you to get through the prerequisite check, even after installing MS Visual Studio Shell 2008.  It ends up the installer doesn’t complete and you have to manually update the following registry values and rerun the Visual Studio Shell installer:

SCSM auth install 1

 

FIX:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\DevDiv\VS\Servicing\9.0
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\DevDiv\VS\Servicing\9.0\VSR\1033

Set SP and SPindex value to 1 and rerun the MS Visual Studio Shell 2008 installer “vs_shell_isolated.enu”.  Now you should see the prerequisite pass.
