No ActiveSync On iPAQ PPC

Hi Guys
Bought an HP iPAQ (hz2190) from a local boot sal
(i know :-(. You only get what you pay for). Works ok except ActiveSync i
missing. No ASync folder- nothing- on the iPAQ. I can swap items via bluetoot
and storage card but cant sync with Outlook. I can and have- downloade
ActiveSync to the PC but need to install it on the iPAQ (cab file?). as fo
reasons unknown its been completely removed. Any ideas anyone as to how i ca
obtain and install ActiveSync onto the iPAQ

Thanks in advance for any help

Best regards

Ed.
