The issue can be found by reading the error message. SAS.EXE is not held in C:\SAS\Sas.exe and hasn't been installed in that location since version 6.
It is in a directory under Programs, in an area identified as SAS Institute in a folder that specifies the version of SAS. Search for it in Windows explorer and adjust the path. Note that since the path will include spaces that you will need to enclose the command line for SAS in double quotes or it won't work.
