Visual Studio Set-up Project

I have created a set-up project for my solution. I have a new assembly version and have flagged it to remove previous versions. However, when I distribute the software, if a machine currently has a previous version installed it simply brings up a message saying they should manually remove any other versions.

If I change the remove previous versions to false then the new program doesn't ap开发者_运维技巧pear to install correctly (although no error is displayed). I've tried changing the ProductCode and that doesn't seem to make a difference.

Can anyone tell me what the required steps are to upgrade a currently installed piece of software are (or point me to a place that does) please?

To get this to work you need to do three steps:

Select in the Solution Explorer your Setup project. Now open the View - Properties Window (not right click Properties).

• Set RemovePreviousVersion to true
• Increase the Version in any place (e.g. from 1.0.0 to 1.0.1)
• Select Yes in the upcoming dialog about changing the product code
