问题
I build an installer, and it is deployed. I need build a patch to upgrade old files with new files. Please help me. Please help me how to do it.
I am using Visual Studio 2010 Ultimate.
Thanks.

Visual Studio doesn't support creating patches, but you can always create major upgrades:
- increase your Product Version, changing the Product Code
- keep the same Upgrade Code
- modify your installer project and build it
- when the new version runs, it will automatically detect and uninstall older versions
If you really want a patch (MSP), I suggest using a free or commercial setup authoring tool.
