Is that where you directed it too?
You should of Browsed to this folder I would think
C:\Program Files\Dell Support Center\bin
The strange part is, it looks installed already
Can you just double check that you did that correctly
EDIT>>Can you take a look if a copy of
dell_support_center[1].msiis found in the following folder
C:\Documents and Settings\all users\application data\dell\
dsc20upgradeIf not, can you do a search on your computer for
dell_support_center[1].msi
When you open Search and select All files and folders
Select the Advanced options and ensure the top 3 selections are checked
