Hi
I have an application that was installed with Installshield 5.5. I've created an msi project that installs the new application on a new PC without problems.
I now need to modify the msi project to be able to upgrade the old application that was installed with Installshield 5.5. Reading the help files suggests using a full release but I cannot see how to do this. Is there a step by step guide anywhere or is this the best way to do this?
Thanks
J

You could read the uninstall command from registry (HKLM\Software\Microsoft\Windows\Current Version\Uninstall\your product) and run it in a custom action to uninstall the old version.
