I make a Setup Project in Visual Studio 2005 for my application. All works well but when I’m going to distribute an update in a new builded version of my application my clients have to first uninstall my application and then reinstall the new one.
I get the following error when I try to install my app again:
Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.
How do I do to make the new release be installed over the old one

Create updates of my Setup project…

The only property pages i can find is from Project->Properties and I can't find that option there...

- Increment the version property, now you will get a message box that prompts you to change the ProductCode and PachageCode. Confirm this with yes.
- Set the RemovePreviousVersions property to true.
Now the previous version of the product will be removed before installing the current version of the setup. Just remember that the ProductVersion property is very importnant here!Chetan Chudasama - MSFT
I'm glad you got the solution so soon, before my workday was ended. Please feel free to post if you have any problems with this solution!

Hi Anders
In VS 2005, select the Deployment project in your Solution Explorer. Then from the main menu choose View->Properties Window (you can also just hit F4 immediately open the Properties pane once you have the Deployment project selected).
You'll see the Version element near the bottom of the pane and the RemovePreviousVersion element near the middle. Once you change you the Version element you'll be prompted to change the ProductCode as well just as PJ. said (thanks PJ! I didn't know this either).
Good luck :)

Meybe, before i'm home a other user with Visual Studio 2005 installed can do it so you will have your solution sooner.
