I have the same error message

. I've tried all sorts of things
suggested by technical forums without success. A very kind man at Serif,
who's software I was trying to install has spent an hour on the phone
trying to sort the problem for me. Even installing
Windows6.0-KB942288-v2-x86 the 4.5 version brings up the same message.
In system configuration it says Windows installer is running and in
sevices.msc it says it is started and is set to manual. Any solutions
would be very much appreciated.
