quartus always crashes and gives the error

[Altera_Forum]

Whenever i run a compilation after the compilation quartus gives the error and stops working

Try re-installing the software. Are you tied to 12.1? I'd recommend using something newer, depending on your chosen target device(s).

Sometimes the easiest way to get around a conflict between Quartus and whatever other software you might have installed is to install Quartus in a virtual machine. 

 That specific error you are getting related to MSVCRT libraries might end up being overly complicated to get around.
