How to make this happen in setup project?
Posted on 2008-06-22
Hi,
I have a c# windows application project to be released. a setup project has been done for this and the msi file works correctly. The only thing pending is: If I reinstall the application over existing installation, I want to see a warning message to remind uninstallation the existing one first.
How to do this in setup project? I am using setup project in visual studio 2005
thanks

If you change the release/revision number (in project properties) the new one will
automatically overwrite the old one, so you don't need to do this.

please clarify what is "existing installation". Same product, previous version? or same version?

The trick is to check the undocumented public property PREVIOUSVERSIONSINSTALLED.
Note: Just FYI, this property is created by Visual Studio not my MSI.

Instead of the custom action, you can add Launch Condition:
NOT PREVIOUSVERSIONSINSTALLED
and appropriate message.
Also, in setup project properties, you have to specify RemovePreviousVersions=Tru

vadimrapp1,
I thought about using the Launch condition also, but the problem with that is that I think it will not prompt the user to decide whether or not to continue with the install. It will simply say something like, "Sorry, no installing for you."
Good catch with making sure the RemovePreviousVersions = True. I completely forgot about that.

Right.
I suggest that you learn best practices with major, minor, and small upgrades, for example here:
http://msdn.microsoft.com/en-us/library/aa370579.aspx
http://helpnet.acresso.com/robo/projects/installshield12helplib/MajorMinorSmall.htm
You probably have to consider the possibility that the user won't uninstall old version, but install the new one into the same directory :-(
