One web created Excel sheet is crashing when calling the _Excel_BookOpen function. "C:\Program Files (x86)\AutoIt3\Include\Excel.au3" (227) : ==> Variable must be of type "Object".: $oExcel.Windows($oWorkbook.Name).Visible = $bVisible $oExcel.Windows($oWorkbook.Name)^ ERRORLocal $oWorkbook = $oExcel.Workbooks.Open($sFilePath, $bUpdateLinks, $bReadOnly, Default, $sPassword, $sWritePassword) in line 225 seems to load the file but no error is set. Is there any way to catch those errors
