Does VSdocman work with VS 2010/2008/2005 Express editions?
No. The Express editions of Visual Studio 2005/2008/2010 don't support add-ins, macros and packages. You need to have VS Standard edition or higher to run VSdocman or any other add-in.
The 14 day trial only counts days when program is actually used, not calendar days. There's no need to reinstall when you decide to purchase the full version.
VSdocman Tip
You can use the TAB key to move between sections in WYSIWYG comment editor.
