dotnet setup : How to uninstall previous version automatically?
Hi, friends,
I created a .msi to deploy my C#.net Windows app. It works fine. However, after a new version is created, the new .msi can not be installed. The syste requires to uninstall previous version first. I will then have to go to Control Panel to remove the old one, and then go back to install the new one. Do we have a way to allow user to remove the previous version and install the new one in one shot? Any reference documents?
In the setup project properties in the IDE, RemovePreviousVersions is what
you set True. You also need to increment the Version in that same list of properties. When you do that, VS will prompt you to change the ProductCode and PackageCode - say yes. The resulting MSI will automatically upgrade older versions as long as they are installed the same way (old and new both "Everyone" or "Just me"). It is an uninstall of the older version, not just a replacement of newer-versioned files. -- Phil Wilson [Microsoft MVP-Windows Installer] Definitive Guide to Windows Installer http://apress.com/book/bookDisplay.html?bID=280 [quoted text, click to view] "Andrew" <Andrew@discussions.microsoft.com> wrote in message news:92AEE958-674E-4E44-8980-EAB532684591@microsoft.com... > Hi, friends, > > I created a .msi to deploy my C#.net Windows app. It works fine.

Thanks, Phil, it worked for me. But, during installation, it did not notify
me that there was an older version installed and did not ask me if I decided to remove the it or not. In another word, it worked as if the previous version did not exist at all. Do we have a way to notify a user the pre-existing version and confirm with him/her before remove it? Thanks again... [quoted text, click to view] "Phil Wilson" wrote:

There isn't really a good way to do this that I can find. I looked at
inserting an extra dialog into the user interface, but you can't make displaying it conditional. If the search at the start of the install detects an older version, it creates the PREVIOUSVERSIONSINSTALLED property, case-sensitive. I couldn't find a good way to use this in a dialog with a Cancel button. There are ways to do this with other tools or editing the MSI file manually with Orca, but nothing standard exists in the IDE. -- Phil Wilson [Microsoft MVP-Windows Installer] Definitive Guide to Windows Installer http://apress.com/book/bookDisplay.html?bID=280 [quoted text, click to view] "Andrew" <Andrew@discussions.microsoft.com> wrote in message news:EC857473-F186-4B60-95F5-2C595C2AEF59@microsoft.com... > Thanks, Phil, it worked for me.
