Hi all,
I'm facing quiet a similar problem to what mayurkotlikar was facing.
I have a version 1.1 which is already with the user. Now I have developed version 1.2.
Now the new installer should:
1) Detect whether the version 1.1 is present on that system.
2) If present, start with the uninstall of version 1.1
3) After uninstalling the entire application, automatically start with the installation of the new version 1.2.
Observer here that for the new version 1.2 to function there has to be no trace of 1.1 left on the system. Basically, 1.2 has a totally new architecture with new files which can clash with the components of 1.1 with dire consequences. Hence, a 're-install' of the new version over the old would not be possible here.
Any kind of help would be greatly appreciated.
Thanks for taking time out to read this.
Regards,
ANIKET.

I got the solution for that; putting it here in case if somebody needs it:
1. I used the same GUID as the earlier installer.
2. I added the inbuilt ComponentReinstall() to OnMaintUIBefore().
3. Since the GUID is same for the installer and i have incrementing the major version, i get the Maintenance UI, where i am askd to upgrade from 5.x to 6.X.
If is select to upgrade then the previous installation is removed and 6.X installed and since the 5.x files stil in running, i am propted to reboot.
It worked for me!!
