Disha, you need the command "XeLaTeX" [...]



Definitely not!  The command is "xelatex", not "XeLaTeX", as Norbert
already pointed out.

The latter only works on old-fashioned operating systems which are
unable to distinguish between uppercase and lowercase letters.


More accurately, the latter works only on intelligent, modern, operating systems that intentionally ignore case when parsing commands.  See page 23 of The TeXbook, where Don writes :
Usually the operating system prompts you for a command and you type ‘TeX’ or ‘run tex’ or something like that.
Note you type ‘TeX’, not ‘tex’.
