how to force multiple apps to install the the same program files dir using publish
How to force multiple small apps to use the same \Program Files\ sub-directory in an install using publish in VS2010 c# the reason is shared SQL Server Express databases
an answer was given, but I still need to know where Viewing "Target System on Local Machine" is in the publish properties or wizard, or where it is so I can set it
"You can set a default for the Application Directory by
Viewing "Target System on Local Machine"
right clicking on "Application Folder" and selecting properties.
Set the value of DefaultLocation to the directory where you want the application installed.
Also set the flag AlwaysCreate to false"
