i am trying to install some software and it requires removing the following file:

• cd %SYSTEMROOT%\assembly\GAC
• rename Microsoft.Office.Interop.Outlook Microsoft.Office.Interop.Outlook.Old

the problem is when i do the rename it looks like its successful but it doesn't seem to actually delete Microsoft.Office.Interop.Outlook

i tried to explicitally do:

 del Microsoft.Office.Interop.Outlook 

and again it looks like it works but then when i do a "dir" i still see that file.

Do you have any suggestions on why this wouldn't allow me to delete this file. I have outlook closed when i am doing this so i wouldn't think outlook is locking the file.
