Released August 25, 2011 for Design Office 9, Service Release 1c
Starting with version 9.0 of the program, if you chose to retain your database files from a previous installation, the program would be unable to open certain project files. New files could also experience problems when trying to design. This would also cause the program not to run due to incompatible standard wall file, a problem that was partially rectified with Change 103 in version 9.11 below.
