Sounds like:

• Desktop directory was pathed wrong
• Desktop folder didn't exist, unable to save shortcut
• Once unable to save shortcut, couldn't read bytes
• Remaining errors were attempts to index into bytes for file that couldn't be read

So, instead of $ShortcutFile = "$env:HOMEPATH\Desktop\GW2TacO.lnk" I should move to reading [System.Environment]::GetFolderPath("Desktop") instead, as the Desktop folder may be moved via Library functionality and this should track it down.
