Hi, I am new to packaging and i am stuck at a point. I am doing a package for an application and it must uninstall the already installed version of that product which is not an msi....can it be done by performing some custom action?? or is there any other way to do that.
you can create a custom action to handle the following items: 1. check if the old product exist or not? (identify it according to some file version or registry) 2. if yes, delete the old product(delete the all installed files and registry directly)
Thanks for the reply... The problem is I don't have the version or registry values of that application:confused::mad: . I just know some files that exist..so can i perform a system search and then if it is found...can i invoke the uninstall.exe in that folder??
I found in some previous forums and they said that by writing a VBScript we can do that...but i don't have knowledge about that....can someone let me know where I can get the VBScript for my problem....

You could check for the install string under HLKM\Software\Microsoft\Windows\CurrentVersion\Uninstall and run the uninstall string commandline from there.
