Version conflictHi
I have version 1 of an app already installed on client computers. Now I want to install version 2 of the app while keeping version 1 for now so client can test version 2 while keep on using version 1 for now. When I try to install version 2 I get the message "Another version of the product is installed...". How can I get round this? Thanks Regards I have now changed the product id of the app and recreated the set-up. This
time it goes past the stage where it gave message last time but now it says 'Unable to install because a newer version of this product is already installed.' which is strange as I have just compiled this latest version and it should be the newest. What am I missing?

J> What am I missing? It seems to me that you have smth wrong in our Upgrade MSI table ( http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/upgrade_table.asp ) Did you changed Package GUID? What do you use to build your setup package? -- Regards, Vadym Stetsyak www: http://vadmyst.blogspot.com I did change the package id after my post and before second post. I am using
vs2003 set-up project to create set-up msi. Anything I can do from here?

J> Anything I can do from here? Just a hint you can disable flags in setup project properties. Set to false DetectNewerInstalledVersion If you want to have more control over install process, then setup project is not appropriate for you. As an altrenative you can try using WiX ( http://www.tramontana.co.hu/wix/ ) ( http://wix.sourceforge.net ) I am worried that forcefully installing version 2 could effect working of
version 1. How can .net be convinced that version 1 & 2 are completely different apps and should not be related to each other?

products, but it's up to you to make sure that you can run two versions of the app on the same system. The tricky areas will be items that are shared or should be unique, such as services, folders used by the running app, identical assemblies in the GAC, identical shared files in other places. -- Show quoteHide quotePhil Wilson [Microsoft MVP Windows Installer] "John" <John@nospam.infovis.co.uk> wrote in message news:OXNWMqTzGHA.3880@TK2MSFTNGP06.phx.gbl... >I am worried that forcefully installing version 2 could effect working of >version 1.

There must be others
in the same situation wanting to deliver more than one app from the same base code (basically different generations of the same app). There are no common services or folders in my case though.
