--- Code:
The offending code in C:\Temp\WebBolig 2.0\Forms\Items\SaveList.cs, line 242
Where "sheet" is an Aspose.Cells.Worksheet, that has been populated with data.

241 try {
242 sheet.AutoFitColumns();
243 sheet.AutoFitRows();
244 } catch (Exception err) {
245 System.Diagnostics.Debug.WriteLine(err);
246 }

--- Comments:
The entire application is run from a local drive (C:\) on the PC, the user has administrator rights,
Therefore I don't believe this to be a trust issue (https://forum.aspose.com/t/99027)

On the assumption, that this might be due to certain fonts,
I have made a copy of the fonts installed on the PC in question.
It is a 200MB+ zip file, I am however hesitant to upload this file, because of copyright and redistribution issues.

--- Attchments:
The resulting .xls file is attached, obviously without autosized columns/rows.
