Windows Vista Home Premium Service Pack 1 (build 6001)
Acer Aspire 5720 V1.43

Having a headache here. Basically I reinstalled Vista and because Acer laptops come with McAfee, I then uninstalled that McAfees own tool of removal as well as others.

I then bought Zone Alarm security Suite. Download and Install. It gets to 90% and then windows says ''ZoneAlarm client has stopped working" close program.

I haven't even put my serial in it yet! Can someone please help.
