Failed to open Deployment Admin - Deployment admin Crushed and get error message

Failed to open Deployment Admin - Deployment admin Crushed and get error message.

I tried to open a few times the Deployment Admin includes after restart and every time the screen crushed.

The error message which I got is:

Microsoft.CRM.Tools.Admin.DMSnapin, version= 5.0.0.0... Failed to load assembly when open Deployment manager

I Installed CRM 2011 in Windows server 2008 R 2. because this windows version the solution is to run Deployment manager as Admin (Right click and press “Run as Admin”)

To prevent from running each time as Admin make the next steps

1. To go start Run and press “msconfig”

2. System Configuration apprear. Select Tab Tools



3.

Select Change UAC Setting and press Launch.

4.

Change the Progress to Never Notify.

5.
  Save the form and restart the server and From this current time don't must run Process and Administrator.


Thanks,
