Error “17001 – System error” EDIUS 6 software

My computer is Windows XP Home Edition SP3. I downloaded the trial version of EDIUS 6 and unzipped the folder. I double clicked the SetupManagerForEDIUS.exe file according to the instruction. But file didn’t open. Clicking the Setup.exe threw a "License agreement" window along with an error “17001 – System error". I have Let's Edit software installed on my computer. I have tried installing EDIUS 4 trial version before but uninstalled it. Why am I receiving the error? How can I resolve it?
