Install_addon error!

I downloaded install.addon.m and then create a package now i have install_addon named two file: MLAPPINSTALL file and prj file on desktop. What am i supposed to do with them when i try to call install_addon function in command window i got this error:

Installing smlink...

Extracting archive smlink.r2018b.win64.zip to C:\Program Files\MATLAB\R2018b...

Error using install_addon (line 52)

access denied.

when i click install_addon

"install_addon Install the specified addon to the current MATLAB installation.

install_addon ZIP_FILE.ZIP Install the contents of ZIP_FILE to MATLABROOT."

what is that mean?
