How do I resolve the following message ipdiscover-util.pl can't be launched, you must set execution rights?

I am a newbie with OCS Inventory Management.  My tech skills are in the windows arena.  However, I am attempting to teach my self how use opensource tools such as OCS, Linux OS (RedHat) etc.

The OCS Inventory Server is installed on Windows Server 2016.  The items are listed as Non identified peripherals list.

Any suggestions would be greatly appreciated,

Webster
