What? Pidlshortcut.dll is an icon plugin for Avedesk. You are not supposed to OPEN a plugin, of course it doesn't open. Once its in the correct Avedesk folder, go to Avedesk control panel, at the menu choose "Desklets" >> "Add..." Then another window pops up. In that window find "Pidlshortcut" and click "Add" on the right.
That adds a highly customizable shortcut to your desktop. Right-click on the shortcut and press "Desklet Properties" and in the first tab down the bottom you will see "Effect" drop-down menu. Click on that and choose "SelectionBox".
Replace the other shortcuts....? I guess you could right-click on the desklet and choose "Duplicate" and then customize the new shortcut so it leads to a different location.
