I am working on Pure Install script using INstallShield 2008
If product is already installed in PC(Say 1.0) and when user wants to upgrade to version 2.0.The installation should be like automatically remove the older version first then install newer version.
Currently we are doing this,first the user runs the setup which will first uninstall older version then again user runs the same setup which will install newer version.we should do the uninstall and install in one click of setup.
I found that upgrade is supported in Basic MSI projects or Installscript MSI projects but how it can be achieved in pure Install script projects.
Also There is no need of update it should be uninstall older and install newer one in one click of setup
