As from version 04/2010, the DOConCD is also designed for use with the operating system Windows 7. The DOConCD versions up to 09/2009 may cause problems in the application. In zip archive ‘091202_2_w7.zip’ you will find a setup file to install the required plug-in for the respective system. Procedure: Unpack the zip file and start the setup.exe file in the zip package. It is recommended to close all other running programs – in particular Adobe Reader, Adobe Acrobat or the Internet browser – prior to starting the setup file.

This info "comes" from there .
