On 2 PC system on local area network.
Shortcut of software was set as run as administrator.
This was preventing loading of mapped drive on other PC in drive selection list of drive settings

Nothing Happens when icon clicked

A new windows 10 PC . Shortcut was working correctly till yesterday.
Today it flashed a message saying you buy McAfee Antivirus or use Bitdefender
No other choice . So bitdefender was selected.

Now clicking shortcut did nothing.
If ran as administrator it ran.

Solution:
Right click shortcut. Select properties. Added a user and gave full control rights.
It started working.
