Software Deployment

You will need to provide more information for your question to be answered.

here is the process
I have an application which i need to install it .Its an msi.
1) Before installing it has to check if any previous version of it is installed on the machine if so it has uninstall it and install the new version.
2)At the same time it has to check other application(a different application) is installed on the machine and if so it has to uninstall it that one also..........

You need to learn how to use the appsearch and associated tables... You can set properties based on the results then use those property values in the launchcondition tables or for custom actions etc.

There should be plenty of info on the boards here, here's the msdn info:

Thank you .................

Or use a batch file to do the logic.

REG QUERY HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall | FIND /i "{GUID of app to uninstall}" >NUL

%SYSTEMROOT%\System32\msiexec.exe /x {GUID of app to uninstall} /qn

Jmaclaurin : Thank you very much......................

you can use the upgrade table to delete the older version of the application.

In order to delete the existing application use the app search table and set the property to unisntall it.

Hope this clears

Hi nagaraju,

you can uninstall the previous application via upgrade table and make sure to sequence the standard action RemoveExsistingProducts properly as per requirment.
for the other application(different application) you can do system search such as appsearc and associated tables such as Drlocator,Reglocator,Complocator and use the searchd values in Custom actions or launch condition table as per requirement.

By the way may i known why u are required to remove the other application which is a different application? via your Application.its a dependecy somethin like??????.....

Hey Vbscab,

Jus set the custom action depends upon the Property value to delete the pacakge via product code!

LOL I've been doing this stuff for more years than I care to remember, I *really* don't need packaging lessons, thanks.

mayur_mak : Thanks mayur
Actually its a webex application .....(It has meetingcenter ,outlook,oneclick ,record and player different applications) ..........................the older version has support manager in addition to this .Now they dont want support manager in the new application .So they just want meetingcenter ,outlook,oneclick record and player and by using this we are trying to uninstall the older version of all the four and also support manager. so I was looking to add the uninstallation in one of these mst.Its done now I used batch file which Jmaclaurin explained me ......and its working..
