TruClient Ajax IE - Function Library not located when running from Perf Center

Hi,

I'm using TruClient Ajax IE with Performance Center 11.52.

I've finally managed to create and parametrize a script which uses functions libraries.

Everything works under VUGen but when I upload the script into Perf Center and run I get the following error:

Error -203252: ** 56.1: Call Function SL.OpenChngStatusPopup ** failed - library named 'SL' could not be located.

I've also tried to add the .xml to the script (Extra Files -  Add files to the script...) but still same result.

Now, I've found few mentions in this/other blogs and I understand that xml file of the function library may contain a hard relation to my local HD. Is that correct? Can you please provide me with likely solution? It has to do with copying the .xml into a specific path (in the load generator)?

Thanks in advance!! Ivan
