I am running the diagnostic test " Excel Workbook configuration test" and it fails on the last part of it named "Launch Excel Application". its when the Exceldriver shall launch excel.
I have The correct HPC Pack installed i have tried reinstall booth the HPC Pack and Excel but with no success.
Launch excel manually on the node and check the macro settings in excel (try setting TRUE to thse 2 properties - Enable All Macros and Trust access to the VBA project object model).
