Unattend.txt problem

Does anyone know how to deal with special characters in unattended.txt. I need to run a command in GUIRunOnce which itself needs quote marks. The command I'm trying to run is C:\SOFTWARE\INTELM42\W2KUPDAT.EXE -iC:\SOFTWARE\INTELM42\NETI557X.INF -h "PCI\VEN_8086&DEV_2449 ". The syntax in GUIRunOnce needs to have the whole command within quote marks and it's obviously having problems interpreting the line. I've tried backslashes before the quote marks in the actual command (this works in some programs) but that doesn't help.

 

Now sorted, got IBM to assist

 

Thanks for letting us know. Sorry no one from here was able to help out but glad you did get it working.
