Automatical uninstallation of my already installed program

[vidishasharma]

Hi,

I have installed some program on users machine using msi installer.
Now there is new updated installer available. My problem is as soon as
user tries to install this new installer the previous installed
program should automatically get uninstalled and the the new one
shhould get installed.


How can I achieve this.

Hi,

The key of the anwser is the following properties "Version",
"ProductCode" "UpgradeCode" and "PackageCode" in your msi.
It's been a while since I built an msi package but, if I remember, to
do an "upgrade", you must ansure your 2 msi packages have the same
"UpgradeCode", and different "Version", "ProductCode", "PackageCode".

In addition, you must specify correctly the UpgradeTable in your new
msi

progrom (which I go throgh control panel)
