Error 2 calling a file using application.executeProgram

Hi guys

Can anyone help with this Windows call - I am trying to write the equivallent of this:

PXI -Mode Import -IntegrationId Generic -FilePath c:\Trigold\Generic\Click.xml

…From the c:\Trigold\ directory

Code Used
var program_output = application.executeProgram(‘c:\Trigold\Generic\PXI’,‘-Mode’,‘Import’,‘-IntegrationId’,‘Generic’,‘-FilePath’,‘c:\Trigold\Generic\Click.xml’);

Error Presented

java.io.IOException: CreateProcess: c:\Trigold\Generic\PXI -Mode Import -IntegrationId Generic -FilePath c:\Trigold\Generic\Click.xml error=2

This was working and is now throwing an error - does anyone know what Error 2 is ? and if not can you see any reason why this code snip wont re create this the example which works as a command line call when typed in direct ??

Many thanks in advance

Gordon
