How to uninstall during installation in insall shield
i have built a Merge module using installshield 2010 . i have a built a main install shield using the same version.
i have included that merge module in the main installer For some reasons i have to uninstall the whole product and install the product again during installation . when i double click the .msi(setup) file . it has to uninstall the product first and then install new feature which i have added in the installer
Please can someone help me??
Thank you
