Auto uninstall

Recommended Posts

Hi All,

If the installer finds an earlier version of the software, is there a way to automatically uninstall and proceed the installation of the new version?

Thanks a lot

No, Excelsior Installer cannot do it automatically. But you can implement this functionality by writing your code (e.g. in C), compiling it to a callback DLL and then using it in the Excelsior Installer. 

For the detailed information please refer to the JET User's Guide, Chapter "Deployment Automation", Section "Excelsior Installer", subsection " Callback DLLs" and Section "Specifying Installation Setings", subsection "Extra-facilities".
