Nothing like pressure, but my first Wix Install is being released to clients
on friday and I am struggling to prevent a downgrade. The product id is set
to a guid and the package id to *, the upgrade code it set to the parameter
in the prodcut.
The relevant code is below, I was expecting an error to be displayed if I
tried to install version 4.0.0 on top of version 4.1.0 but I am getting no
such error.
I have run the install with verbose logging but can't find SELFFOUND or
NEWERVERSIONINSTALLED being set, is that expected?
As you can see this code has been adapted from the www.tramonta.co.hu
tutorial, I have also done a search here and can't find anyone else with my
particular issue(but of course my search criteria may be flawed)
Can anyone point me in the right direction please?
Yours in anticipation
Martin
