I've seen that this happens only for services and not for files.
In the uncompressed setup I see folder like this:
foreach Install Files in the setup.{...}\\data\\OFFLINE\\3C33A47B\\723DB1A3\\Myfile.exe
but with the services the names is:
{...}data\\OFFLINE\\c_\\documents and settings\\mauro\\documenti\\visual studio 2005\\projects\\myproduct\\debug\\myservices.exe
foreach Install Service in the setup.
And when the original path contains ".." the folder si empty.
