1. Updater Application Block
  1.1 Exceeding Maximum Path 
  Length
  The Updater Application Block creates a folder hierarchy and files 
  during the download and activation processes. This hierarchy includes folders 
  named using GUIDs, representing application and manifest identifiers. The 
  files created by the Updater Application Block in this hierarchy are subject 
  to the Windows maximum path length of 260 characters. This means that if your 
  application is located at deeply nested path you can encounter an exception 
  when the Updater Application Block attempts to create files in the folder 
  hierarchy. To avoid this issue, you can install your application at a location 
  closer to the root directory. Alternatively you can set the BasePath 
  configuration property for the Updater Application Block. The value entered 
  for the BasePath property is used as the root folder for the folder 
  hierarchy created by the Updater Application Block. If you do not enter a 
  value for this property, the hierarchy is created using the application folder 
  as the root folder. You set the BasePath property by using the 
  Enterprise Library Configuration Console. 
  
  2. Updater Manifest 
  Tool
  2.1 Maintaining the Source Folder 
  Property
  The Application Properties tab of the 
  Updater Manifest Tool contains field labeled Source Folder. You set the 
  value of this field to establish the root folder for the application files you 
  want to add to the manifest. This location is also used when creating a hash 
  value for the files or changing hash providers. The value of the Source 
  Folder property is not saved in the manifest. The manifest contains only 
  the relative path from the Source Folder value to each application file. When 
  opening a saved manifest file, the Manifest Tool may show you a dialog to 
  locate the folder which contains the files specified in the manifest. The 
  folder you select in this dialog will set the new value for the Source 
  Folder property. Failing to specify 
  this value, will open a blank manifest.
Bene... ora mi tocca implementarla al posto della alpha e vedere che 
succede!!!
