User imported a MDB file to CWSuite in Model explorer and cannot open any of its diagrams.
There is no error message, it simply opens Corporate Modeler, but the diagram will not open.
Model is from an older version of erwin Casewise Suite and needs to be upgraded first.
Close all erwin CWSuite.
Open a DOS command prompt as administrator.
Navigate to the Bin Directory were Erwin CWsite (Casewise) is installed.
C:\Program Files (x86)\Casewise\CM10\bin
Type the following:
-username:YourUserName password:YourPassword -upgradedb
-Connection: this is your Casewise connection name, what is display in your Logon window
-Username: this is the Casewise user name, ADMIN is best to use
-Password: ADMIN user password, or the system user that is used to connect
After the database is upgrade please run the same command with Applyfixes
C:\Program Files (x86)\Casewise\CM10\bin>ValidateRepository.exe -Username:ADMIN -connection:Stand-alone -Applyfixes
Once completed you may login to Erwin Suite and you should be able to open your diagrams.
