MicroStation or MicroStation PowerDraft will not start and get Text Window with error message.
System fault: 5 MDL abort in DITEMS Unable to start ditems.ma
Press any key to continue …
The "unable to start ditems.ma" message is fairly generic, but it could be related to a security setting for Data Execution Prevention (DEP) in Windows. In more recent Windows releases, that has been set with additional security to only allow authorized executables to run -- MicroStation/J is probably not one of them (since it was released before DEP security was a factor... yet another reason to look into getting a more current release of MicroStation).
How you change that depends on the OS that you are using. There is some information in this article that might be worth to check with your system administrator(s) regarding that.
