When I install my app using a local or mapped drive it installs correctly.
When I install it using a UNC path, i.e. \\someserver\share, it will install the app but will not write registry changes. The app also shows up in control panel add/remove programs with no size listed. When I run the app it will create the registry keys because they do not already exist but then they of course do not contain the settings I am trying to use with the app.
The Install package includes prerequsites for Windows Installer 3.1 and .NET 2.0 and adds a registry key and subkeys.
Any reason that not using a drive letter would make the reg entries not function.
