If you still find the problem, could you give us error details and we will check it soon.
I am also attaching the lastest (4.4.1.3) dll version of the component Aspose.Cells.dll. you may simply copy it to your specified folder and use it in your project after adding reference to it.
I'm using the latest build of Aspose.Cells. The problem is not vista, is the request for .Net Framework 1.1.4322, wich I installed but Aspose.Cells doesn't found. May be is because I have a 64bits computer, but I can't found a way to bypass the .Net Framework request.
