HOW?: Via RunAsDate open a trial programm in Sandboxie?

[PeterPaul]

Hello together
I have a trial programm that I have to open with a date before 1th January 2013. I want to open it in Sandboxie without to have to chance my PC Date/Time. So I think first to open RunAsDate in Sandboxie and then fix a date before 1th January 2013 in it; then via RunAsDate to open mit trial programm in Sandboxie too.
But I am not able to do so: I can not find the *.exe file for the trial programm.
Can anyone help me please; is there an other way to open the trail programm in Sandboxie with a date before 1th January 2013?
Thank you for your help in advance
Peter
