I've downloaded and installed Prince 8.0 today on a fresh copy of Windows 2008 Enterprise. It got through the installation routine fine, but when I run the program I get the error message "Component COMDLG32.OCX or one of its dependencies not correctly registered: a file is missing or invalid."

Sorry about this, you will need to run "regsvr32 comdlg32.ocx" as administrator to fix the problem. (In older versions of Windows this did not require administrator privileges, now it does. We are working on a new GUI that avoids this issue). Note that you can still run Prince from the command-line, by running c:\Program Files\Prince\Engine\bin\prince.exe

Thank you, this fixed the problem.
