InstallAware

I have a setup that in my manual test works but in my integration with TFS Builds where the path come from variables (I've used a compiler variables #buildpath# in file names) have some problem when is like:

{...}\\BuildType\\..\\Sources\\..\\Binaries\\Debug\\{...}

I've seen that this happens only for services and not for files.
In the uncompressed setup I see folder like this:

{...}\\data\\OFFLINE\\3C33A47B\\723DB1A3\\Myfile.exe

foreach Install Files in the setup.
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.
