Localized version of the Autodesk Design Review 2009 Release candidate (RC) are affected by a problem that will lead to the loss of the localized user interface. Users affected by the issue are German and Japanese Autodesk Design Review 2009 RC applications.
The issue can be averted by removing all previous versions of Autodesk Design Review prior to the install of the 2009 version. Failing that, a Repair install would also resolve the issue if Autodesk Design Review 2009 RC has been installed without the prior removal of previous versions of Autodesk Design Review.
The localized versions have received a new build and the issue will no longer exist in the official release build for German and Japanese users.
