An attempt to enable myLittleAdmin or ASP.NET Enterprise Manager on Tools & Settings > Server Components fails with this error:

Can't set component parameters:defpackagemng failed: Execute websrvmng --add-application --vhost-name=(default) --app-name=mla2000 --scripts=asp --enable-parent-paths=true --app-pool=plesk(default)(pool) --asp-codepage=1252 "--path=C:\Inetpub hosts\sqladmin\myLittleAdmin\2000" failed with error code 1: Filename:
Error: Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'PageHandlerFactory-Integrated' In module
Exception type: System.Runtime.InteropServices.COMException


The problem has been fixed in Parallels Plesk Panel 11.0.9.

The fix for Plesk 10.4.4 is attached to this article. In order to install it, follow these steps:

  1. Save the files aspsqladmin.dll, mylittleadmin.dll, and websrvmng.exe to the %plesk_bin% directory, in a safe location.
  2. Download the archive to the server, unpack it, and copy the unpacked files to %plesk_bin%, replacing the existing files.
