Problem: Code written with ArcSdl does not work correctly or fatals
An application written in ArcSdl does not work correctly or quits with a fatal error.
The machine is running incompatible versions of ArcInfo and ArcSdl.
Solution or Workaround
Install matching versions of ArcInfo and ArcSdl.
An application may compile under a version of ArcSdl even if different from ArcInfo, but this is not supported and should be considered very unstable.
