Windows 98 compatibility

i just deploy my application and i get an error on a windows 98 SE machine (fresh install - ie6):

i can't debug it, but reading the code i think this append instancing the cells library.

the function i call is in a component: that function is used somewhere else in mycode with a flag saing if create the xls files or not. in this case i'm not creating the xls so meaning i'm not using the cell component at all i'm just declaring it in the component variable and imports aspose.cells library in the object doing:

Imports Aspose.Cells

so i think that the imports load some library that win98 do not have?

does the aspose.cell component is compatible with 98? first of all

do i need some library ?
