Convert existing XP application to work on Windows 7

An open source PDF Printer which works in Windows XP, currently will not work in Windows 7. This needs to be updated to work with Windows 7 and Vista and rebranded to a new name. Specification: - Application to be compiled in Visual Studio 2008, with project files updated accordingly. - An installation guide needs to be created, mentioning any required dependencies for VS2008 compilation. - Filenames, titles and printer name need updating in PDF Printer. - Installer for this PDF needs to be integrated into an existing NSIS script. If you would prefer Inno, this is possible. - Uninstaller also needs to be generated. - Needs to work on Windows 7, Windows Vista and Windows XP. Message me if you would like to know the open source applications or if you have any other questions.
