Fail in installing Rhino7

I am in trouble while installing. It keeps telling me

“error writing to file: C:\Program Files\Rhino 7\System\Compat.exe Verify that you have access to that directory. (1310)”

I have checked anything I can but yet there is no hint. By the way, that compat.exe file is strange. As I checked that through cmd attrib there is no file name that so it is not the file hidden problem.
