The link on the left in <Action List> tab, "Open Admin$", show "javascript:runApp('explorer.exe \\\\computer\\admin$','false');"
I found a way to resolve these issue by modifying <Action> Field of <Open Admin$> record from <dbo.tsysactions> table in <lansweeper32> database
The value was "explorer.exe \\computer\admin$"
You should add "{" at the beginning of "computer" and "}" at the end of "computer"
Then it become : "explorer.exe \\{computer}\admin$"
Refresh the "Action Screen" to see the change
