I have been looking all over for documentation on this and have been unsuccessful.
I am running a test plan through the runtime.exe and inside it, it changes the option set through the optionset: key word in the plan. Every time I try to run the plan it says "Unable to load C:\directory1\directory2\directory3\filename.opt".
If I open that option set and run it then bombs on the other options set I have defined in the plan. So the only way to have a plan run through the runtime.exe is to have that optionset open and you can not change it? Does anyone know why that is? I am able to do that when running the test plan through the SilkTest Classic (partner.exe).
