No doubt there are entire teams of people dedicated to understanding the Microsoft Windows installer system (.msi files) but for me it is just a means to an end. I didn't find it a particularly accessible technology so from the point of view of someone interested in deploying the output from a Visual Studio 2008 project onto end user systems, here are a couple of the gotchas I came across.

One of KeePass Password Safe's strengths is the ability to install plugins. This keeps the main application simple and hence (potentially) more secure. Developing plugins for KeePass and installing them has always been pretty straight forward but starting with KeePass 2.09 there is a new plugin format which now means that your plugins will not need to be re-compiled every time a new version of KeePass is released. If enough plugin authors migrate their plugins to this new format then this should gradually remove some of the barriers that discourage users from promptly upgrading to the latest version of KeePass.

This article outlines how I moved my KeeICE plugin to the new format and shows how the PLGX build can be integrated with Visual Studio. (KeeICE is the KeePass plugin that the KeeFox firefox add-on communicates with - a beta release is (still) not far away).
