Thanks for th eresponse.

I think there's enough RAM - 2 gig. Certainly PLE is working on an XP laptop of mine, with the same RAM.

I'm at work at the moment and the laptop is at home, so I cannot yet post the text of the error message. However said message was encountered when installing the application, was somewhat obscure, but seemed to insist that it was not very happy to have encountered something that was Vista, or was not XP.

I'll post the entire message later tonight. Further thoughts & experience welcome.
