When this add-in is in production, I want clients to be able to download a new version and install it using one installer. Currently, when I try to run a new installer with a previous version already installed , the installer raises an error saying that the add-in is already installed.

How can I uninstall an old version if it exists automatically without an uninstall wizard , and then install the new version, all from the same.

How can I uninstall an old version if it exists automatically without an uninstall wizard , and then install the new version, all from the same. EXE script? I am using InnoSetup to encapsulate a few other installers. I know I can run an the uninstall script which InnoSetup creates, but then it deletes the target directory before the new files are installed thus, the installer errors.

Thanks for the help.
