symlink() cannot create symlink (5 replies)

Hi,

First time I using Wamp
my problem is when I starting wamp (3.1.9 x64)

this error showing in wamp64/logs/php_error

PHP Warning: symlink(): Cannot create symlink, error code(5) in c:\wamp64\scripts\wampserver.lib.php on line 157


ps. its in side wampserver.lib.php -> switchPhpVersion(), is its wierd ? becase my another computer look like does not run this function while wamp start

Im sry to my poor english
