Advanced Admin Console error issue

Hi,
I have installed Advanced Admin Console Adding: Version 0.5.0 Beta. I also have Windows Power shell 1.0 installed to run my data conversions.
I have a Windows XP operation system. I provided these details in case it might help with the problem that had come up on my computer.
The error is as, “Advanced Admin Console: Couldn’t run power shell. exe. ”
I have no idea what this means. I have tried running a test conversion to see if that helped, but failed. Is it a problem with the Power shell program installation? Or is it to do with the Advanced Admin Console Adding setup? Has anyone else faced this problem? Please help!
Thanks.
