Hi All,

I have one Application setup(MSI) v1.0.0.1,that is developed in VS 2005 using C#.
Installer.cs class contains install() and uninstall() functions.
Then i created one more setup(MSI) setup for same app'n, i.e, V1.0.0.2
Here i set the Removepreviousversion option as TRUE and installallusers as TRUE.
and setup version also changed to 1.0.2(previously its 1.0.1 for V1.0.0.1)
and I updated the Assembly version and assembly file version to its

While installing v1.0.0.2 (v1.0.0.1 already installed) it is not showing any exceptions(i placed try/catch in code) but new version functionality is not working.
And i checked manually, i mean i uninstalled v1.0.0.1 manually and installed the v1.0.0.2 ,then its working fine.

Is there any problem with code or setup settings?

im trying to find out the solution and
can any one help me for this scenario.

Thanks in advance.
