I am looking to upgrade a project created with a previous version of InstallShield. When I do a major upgrade using the normal IDE method I lose the entry in Add/Remove Programs. Therefore I am prepared to cut my losses, what I want to do is to detect previous versions and simply halt the installation telling the user to uninstall manually first.
However I can't figure out when to do this. I have put code in AppSearch, OnBegin,OnCCPSearch etc but I still see the dialog box "a previous version was detected, do you wish to upgrade"... how/where can I insert my InstallScript code before this point?
Thanks in advance,
Colin

I belive you can turn off this message in the Relese > Upgrades settings.
It should also go away if you change the ProductCode which will result in a Major Upgrade.
