When need to Customize form but can't start program script

Why you want to change the script if you only want to change the form?

Use "Edit Form" instead.

Check your developer parameter template as usually a file "otepad.exe" does not exist in windows directory.

I check already that ok but I can not to do script when I copy current to P-VRC

I think in the developer's parameters it should be notepad.exe of which 'n' has been missed out some how. So change it to notepad.exe and it should be okay now.

1) It shows "c:\windows\otepad.exe", maybe the problem is this, change it to "notepad.exe"
or
2) Because you want to customize a standard session and you don't have sourcecode of this session. You only have an object code (a binary code).
