There are a few problems;
1. Where you say to place the .dll files, that some plugins need manually placing, you mention the default installation path for Plus only. Some people have custom install paths, so it should have a footnote telling people if they have a custom install directory the need to improvise their directory to suit.

2. Not all plugins are listed in add/remove programs, you really should say that plugins can be disabled in Main Messenger Window > Plus > Preferences > Plugins. Or the method of deleting the .dll file\files of the plugin and the need to restart messenger after deleting the dll file\files.

3. Some VB plugins need to be manually registered using regsvr32, so you need to cover the need to Start > Run > regsvr32 and link to the path of the dll file you need to register. You could have this in a section of what to do if a plugin doesn't work or something like that.

4. I'd mention the need to look in the readme of the file if you can't install the plugin or it does not work.

5. Also I think it would be best to cover the .reg files that often accompany the .dll file\files.
