That thing you need to manage when you are creating the setup at that time there is some option for that and you can also manage it through registry entry. so install time you need to check that registry entry if the entry is found then you can remove that version and then install new one

The setup is installed in the same directory, when you install new version it may replace the older one

hi,

You should be able to read the uninstall string from the registry, given the AppId (i.e. the value you used for AppID in the [Setup]-section). It could be found under Software\Microsoft\Windows\CurrentVersion\Uninstall\{AppId}\ (could be either HKLM or HKCU, so best check both) where {AppId} should be substituted with the actual value you used. Look for the UninstallString or QuietUninstallString values and use the Exec function to run it from your InitializeSetup() event function.


and removed non-working alternative solution using a [Run]-section entry with {uninstallexe}


Thanks,
