HPSM Installation on Windows 7 just for PD Demonstration

Hi Experts,

I would like to demonstrate Process Designer to one of my clients from my laptop which is having windows 7.

I am not getting which SQL installable should I use to do minimal DB usage. I have nothing to do with SQL server. Just to demonstrate Process designer within 4 days.

Please let me know how should I proceed for that?

I am HPSM v9.40 and v9.41 both.

Waiting for your valuable inputs regarding the same.

Regards,

Avi
