After running the installer for AutoCAD LT 2017 you may get a host of error messages warning about missing DLL’s. To fix this you can either download the full installation from Autodesk, go to the extracted folder and run the Visual Studio installer, normally something like C:\Autodesk\AutoCAD_LT_2017_NWL_English_Win_64bit_dlm\3rdParty\x64\VCRedist\2015\vcredist_x64.exe

If this does not work for you chances are you are missing a 3rd party pre-requisite. Be sure to check the requirements and install the correct version relevant to your installation 64 bit or 32 bit.
