In Ep budgeting application i got two version 6.1.1 and 6.4, when 6.1.1 version is present in the system i have to install 6.4 that means when i install the application it is to be upgraded from 6.1.1 to 6.4 with out uninstalling the 6.1.1

While launching it is asking for activation key, according to my requirement after installtion activation should be performed and before uninstallation de-activation should be performed.

Here 6.1.1 source is a setup.exe

Yes I think it is very much possible. I suggest you must first check the presence of the older version using app-search (though not mandatory but a good practice). Then include a CA to uninstall the setup.exe using a command line that is supported by the .exe or simply calling the Uninstall.exe (if at all one exists). You can first try uninstalling it manually and then include the same in your package.
The important thing is the placing of the CA. Also it must add that it may not be the cleanest of uninstalls like the ones possible when working with a MSI/MST.

Others, can you help with any others techniques.

Yes.! This solution seems pretty good. in the same way i keen to implement like..
trystrap_9.0.exe installed in base system,need to uninstall trystrap_9.0 before installing trystrap_10.0.msi.
work flow:
1) search for particulauar folder if exists go for instalation , if not folder exists terminate installation.
2)if exists go for uninstall before installing new one.

u have mentioned for uninstalling include CA, where exactly i will include immidiate or execute.
