I hope this is right group for this. I have install setup and .msi and it work good but i canot upgrade program after install on one machine. If they install program and then i ship new .msi the setup.exe say prior version already install you must remove and install later. I change the RemovePreviousVersion to true and also generate new upgrade code, but it is same result. Maybe someone can help.

Having the same UpgradeCode is what makes the upgrade work. If they are different between old and new setup that's a reason why it will fail. The ProductCode is what needs to change.
You need to increment the Version property in the setup project, then it will prompt you to do the right thing.

i don't install any .net framework. This is install already version 3.5 SP1. My install is for custom program i wrote in C# .Net.

Hi MinguiSun,

I am moving this thread from Base ".NET Framework Setup" forum to the "ClickOnce and Setup & Deployment Projects" forum, since the issue is related to deployment. There are more deployment experts in the "ClickOnce and Setup & Deployment Projects" forum.

Thanks
